You have two blocks, with respective masses of 8 kg and 12 kg sitting next to each other on a table. You decide to move them both together, and push on the 8 kg block with a net force of 120 N such that it pushes the 12 kg block along with it.

a. Find the acceleration for both blocks.

b. Will both blocks feel the same net force? Explain.

c. Draw a force diagram on the 8 kg block, and find a force equation for the horizontal forces acting on it.

d. Draw another force diagram on the 12 kg block, and find a force equation for the horizontal forces acting on it.

e. Explain how Newton's 3rd law applies to your answers in part C and D.

The next two questions refer to the following physical situation: Two blocks (masses m1 = 30 kg and m2 = 7 kg) sit atop one another as shown below. The coefficient of static friction between the blocks is μs= 0.32. There is no friction between the lower block and the surface on which it rests. A constant external force F is applied to the lower block. What is Fmax, the maximum magnitude of this force such that the upper block does...

Two blocks of masses m1= 2.00 kgand m2= 4.10 kg are released from rest at a height of h= 4.40 m on a frictionless track. When they meet on the level portion of the track, they undergo a head-on, elastic collision. Determine the maximum heights to which m1 and m2 rise on the curved portion of the track after the collision.

An Atwood's machine consists of blocks of masses m1 = 9.1 kg and m2 = 20.0 kg attached by a cord running over a pulley as in the figure below. The pulley is a solid cylinder with mass M = 8.00 kg and radius r = 0.200 m. The block of mass m2 is allowed to drop, and the cord turns the pulley without slipping. a) Why must tension T2 be greater than T1 B) what is the acceleration of...
