Bob, who has a mass of 71 kg , can throw a 480 g rock with a speed of 31 m/s . The distance through which his hand moves as he accelerates the rock forward from rest until he releases it is 1.0 m. a. What constant force must Bob exert on the rock to throw it with this speed? b. If Bob is standing on frictionless ice, what is his recoil speed after releasing the rock?

A freight train consists of two kg 1000.8 4 − × engines and 45 cars with average masses of kg 1050.5 4 × . (a) What force must each engine exert backward on the track to accelerate the train at a rate of 2 –2 m/s 10.005 × if the force of friction is N 1050.7 5× , assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains...

Problem 4.39
Two crates, one with mass 4.00 kg and the other with mass 6.00 kg, sit on the frictionless surface of a frozen pond, connected by a light rope (Figure 1). A woman wearing golf shoes (so she can get traction on the ice) pulls horizontally on the 6.00 kg crate with a force F that gives the crate an acceleration of 290 m/s 6.00 kg よ 00 kg T he woman is pulling two c rope that connects...

5. A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 N on him. The mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 backward. (a) What is the force of friction between the losing player's feet and the grass? (b) What force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg?...

Two uniform solid spheres have the same mass, 1.65 kg, but one has a radius of 0.256 m while the other has a radius of 0.844 m. For each of the spheres, find the torque required to bring the sphere from rest to an angular velocity of 357 rad/s in 10.5 s. Each sphere rotates about an axis through its center. a)Torque on sphere with the smaller radius. b)Torque on sphere with the larger radius. c)For each sphere, what force...
