(b) How much force does the astronaut exert on his chair while accelerating straight up at 10 m/s^2?

A 75 kg archer on ice skates is standing at rest on very smooth ice. He shoots a 450 g arrow horizontally. When released, the arrow reaches a speed of 110 m/s in 0.25 s. Assume that the force of the bow string on the arrow is constant.b. What is the archer's recoil speed?

The foot of a 55 kg sprinter is on the ground for 0.25 s while her body accelerates from rest to 2.0 m/s. (b) What is the magnitude of the friction force?

Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 12 N force applied to the 1 kg block. (b) How much force does the 2 kg block exert on the 1 kg block?

A 1000 kg car is pushing an out-of-gear 2000 kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4500 N. Rolling friction can be neglected. (a) What is the magnitude of the force of the car on the truck?

Taylor (150 lbs.) and Josh (200 lbs.) are standing on frictionless ice. Taylor pushes on Josh. During the push which person exerts the greater force on the other?

Taylor (150 lbs.) and Josh (200 lbs.) are standing on frictionless ice. Taylor pushes on Josh. During the push who experiences the greater magnitude of acceleration?

A book is at rest on a horizontal table. The main forces acting on the book are the normal force from the table and the weight of the book. What is the best description of Newton's third law reaction force to the weight?
