What net force would be required to give a mass of 42.32 kg an acceleration of 7.28 m/s/s? 

A net force of 43.0 Newtons will cause a mass of 4.30-kg to accelerate at a rate of ____ m/s/s 

 A 7.5-kg object is moving to the right with a constant velocity of 2.0 m/s. The net force encountered by the object is ____. 

 A net force of 400.0 Newtons will cause an object to have an acceleration of 7.72 m/s/s. Determine the mass of the object. 

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 82.5-kg Stapp at 441.0 m/s/s (the highest acceleration tested by Stapp)? 

The rising concern among athletic trainers and health advocates (and parents) regarding concussions and multiple concussions among high school football players has prompted numerous studies of the effectiveness of protective head gear and the forces and accelerations experienced by players. One study suggested that there is a 50% chance of concussions for impacts rated at 75 g's of acceleration (i.e., 75 multiplied by 9.8 m/s/s). The average head impact in football results in 22 to 24 g's of acceleration ... but not all head impacts are equal.

If a player's head mass (with helmet) is 6.45 kg and considered to be a free body, then what net force would be required to produce an acceleration of 75 g's? 

Sophia, whose mass is 55.2 kg, experienced a net force of 1470 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. 

As Bishop approaches the stop sign, he applies the brakes, slowing his 1700-kg car at a rate of 2.13 m/s/s. What is the magnitude of the net force upon his car? 

A rightward force of 17.0-N is exerted on a block to accelerate it across a friction-free surface. It accelerates at 4.59 m/s/s. If a second block of identical mass is dropped onto the first block, then what is the acceleration when the same 17.0-N force is applied to it. (Assume that there is no sliding between the first and second block.)
