Captain John Stapp of the U.S. Air Force tested the human limits of acceleration by riding on a rocket sled of his own design, known as the Gee Whiz. What net force would be required to accelerate the 79.4-kg Stapp at 447.0 m/s/s (the highest acceleration tested by Stapp)? 

Sophia, whose mass is 49.1 kg, experienced a net force of 1750 N at the bottom of a roller coaster loop during her school's physics field trip to the local amusement park. Determine Sophia's acceleration at this location. 

The shipment of the new physics supplies have arrived. They are placed on the freight elevator and transported up to the third floor for delivery to the physics rooms. The free body diagram at the right depicts the forces acting upon the freight elevator as it begins its ascent through the elevator shaft. The values of the individual forces are:

F_tens = 2900.0 N

F_grav = 2340.0 N

F_norm1 = F_norm2 = 240.0 N

Use the force values to determine the …

While skydiving, Dee Selerate opens her parachute and her 48.5-kg body immediately accelerates upward for an instant at 8.59 m/s/s. Determine the upward force experienced by Dee during this instant.

Brandon is the catcher for the Varsity baseball team. He exerts a forward force on the 0.146-kg baseball to bring it to rest from a speed of 28.0 m/s. During the process, his hand recoils a distance of 0.118 m. Determine the ...

The Harrier Jump Jet was one of the first fixed wing military jets designed for vertical takeoff and landing (VTOL). It is capable of rotating its jets from a horizontal to a vertical orientation in order to takeoff, land and conduct horizontal maneuvers. Determine the vertical thrust required to accelerate a 8240.0-kg Harrier upward at 0.475 m/s/s.

A 7.41-kg object experiences a horizontal acceleration of 5.30 m/s/s when a 57.2-N force is exerted upon it. Determine the force of friction that opposes this object's motion.

While skydiving, Dee Selerate opens her parachute and her 54.5-kg body immediately accelerates upward for an instant at 7.27 m/s/s. Determine the upward force experienced by Dee during this instant.

A 72.6-kg skydiver (parachute mass included) opens her parachute and experiences 1680.0 Newton of air resistance.

Consider the free-body diagram for a 4.83-kg object accelerating across a surface. The applied force is 57.5 N and the coefficient of friction is 0.397. Determine the … 

A 36.0-N force is applied to a 7.8-kg object to move it with a constant velocity of 1.5 m/s across a rough, level surface. Determine the ...

Dexter Eius is running through the cafeteria when he slips on some mashed potatoes and falls to the floor. (Let that be a lesson for Dexter.) Dexter lands in a puddle of milk and skids to a stop with an acceleration of -4.00 m/s/s. Dexter weighs 759.0 Newtons. Determine the coefficient of friction between Dexter and the milky floor.

Ms. Sterling hopes to move a box full of Physics books from her office to the parking lot. The weight of the box of books is 185.0-N. The coefficient of static friction between the box and the office floor is 0.499. What force must Ms. Sterling exert on the box to set it into motion?

During his shift at the Home Depot, Matt exerts a 836-N force upon a 150-kg crate to accelerate it across the loading room floor. If the coefficient of kinetic friction is 0.431, calculate the acceleration of the crate.

A 1190-kg car locks its wheels and skids to a stop across an asphalt surface. The coefficient of friction between the surface and the tires is 0.897. Determine the acceleration of the car.

Malachi has fallen into a bit of a power struggle with Foxy, his 45.0-kg Golden Retriever. He is applying a horizontal force to accelerate Foxy across the lawn. What force (in Newtons) must be applied to move Foxy with a constant speed of 0.53 m/s? The average coefficient of friction between Foxy and the lawn is 0.506.

Mr. H takes his class next door to the community ice rink for a Physics lesson. Anticipating that something phenomenal will soon be happening, Avi (m = 81.0 kg) and Camila (m = 55.8 kg) quickly volunteer. They stand 20 feet apart, holding the ends of a lightweight rope. On Mr. H's cue, Camila pulls on the rope while Avi maintains a steady grip. Avi begins accelerating towards Camila with an acceleration of 0.773 m/s/s.
