A 110 g ball of clay is thrown horizontally with a speed of 11.0m/s toward a 950 g block resting on a frictionless surfa
A 110 g ball of clay is thrown horizontally with a speed of 11.0m/s toward a 950 g block resting on a frictionless surface.It hits the block and sticks.The clay exerts a constant force on the block during the 8.00 ms it takes the clay to come to rest relative to the block.After 8.00 ms,the block and the clay are sliding along the surface as a single system.
1.What is the force of the clay on the block during the collision?
2.What is the force of the block on the clay?
