1. A 400g Block with an initial speed of 80cm/s slides a long a horizontal tabletop against a frictional force of 0.80N.
A) How far will it slide before stopping?
B) What is the coefficient of friction between the block and the tabletop?
2. A 50kg block rests at the top of a smooth plane whose length is 2.0m and whose length is 2.0m and whose length is 0.5m. How long will it take for the block to slide to the bottom of the plane when released?
3. A 6.0lb block rest on a smooth plane inclined at an angle of 20 with the horizontal. The block is pulled up the plane with a force of 30lb parallel to the plane. What is its acceleration?
4. A 2.0 Ton elevator is supported by a cable that can safely support 6400lb. What is the shortest distance in which the elevator can be brought to a stop when it is descending with a speed of 4.0ft/s?
5. A 50kg block is placed a smooth tabletop. A horizontal card attached to the block passes over a light frictioness pulley and is attached to 4.0kg body. Find the acceleation and the tension in the card when the system is released?
6. Two boddies having masses M1=30g and M2= 40g are attached to the ends of a string of negligible mass and suspended from a frictionless pulley. Find the acceleration of the bodies and the tension in the string?
7. Consider the object on a horizontal frictioness plane, acted upon by a single horizontal force.
A) If the mass is 1g and the force is 1dyne, the acceleration is ______?
B) If the mass is 1g and the force is 5dyne the acceleration is________?
