A mass m1 = 3.2 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m2 = 4.3 kg which hangs freely from the string. When released, the hanging mass falls a distance d = 0.86 m
1. How much work is done by gravity on the two block system?
2. How much work is done by the normal force on m1?
3. What is the final speed of the two blocks?
4. How much work is done by tension on m1?
5. What is the tension in the string as the block falls?
6. The work done by tension on only m2 is: (Positive, Negative, Zero)
7. What is the NET work done on m2?
A toy car X of mass .200 kg moves along a frictionless surface with a velocity of .180 m/s. It collides with another toy car Y, with the mass .250 kg and a speed of .130 in the same direction.
A 100-m-long train accelerates uniformly from rest. If the front of the train passes a railway worker 166-m down the track at a speed of 21 m/s, what will be the speed of the last car as it passes the worker.
What is the greatest mass that can be accelerated upwards at 2.9 m/s2 if the stress in the cable is not to exceed the elastic limit of the cable, that is 2.2 108 Pa.
