Sample Class Problems-Force and Acceleration Prob#l: Two people are pushing a stalled car (the mass of the car is 1850kg). One person applies a force to the car, while the other applies a force of 395N. Both forces act in the same of 560N also acts on the car, but in a direction opposite force arises because of friction and the extent to which the pavement opposes Find the acceleration of the car. direction. A third force to that in...

After rounding second base, a baseball player with a mass of 77 kg slides into third base. The coefficient of kinetic friction between the player and the ground is 0.42. What is the magnitude of the friction force acting on the player? If it takes 1.3 s for the player to come to a rest at the base, what was his velocity when he initiated his slide? Suppose you are pulling a 4.2-kg block across a rough, horizontal surface with...

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...
