When starting a race, a 55.0-kg-mass sprinter exerts an average force of 635 N backward on the ground for 0.560 s.
What is the sprinter’s speed after the acceleration?
How far does the sprinter move during the acceleration?
A 1 100.0-kg artillery shell is fired from a battleship, and the shell is accelerated at m/s2?
What is the magnitude of the net external force exerted on the shell?
What is the magnitude of the force exerted on the ship by the shell’s acceleration?
A truck collides with a car and, during the collision, the net force on each vehicle is equal to the force exerted by the other vehicle. The mass of the car is kg and the mass of the truck is kg. The magnitude of the truck’s acceleration is 8.63 m/s2. Find the magnitude of the car’s acceleration.
