Homework Statement
1st example:
A 10 kg block is pushed up a ramp at a constant speed of 5.7 m/s. The ramp makes an angle of 30 degrees to the horizontal and the ramp is frictionless. The block is released and allowed to slide up the ramp until it stops. What is the magnitude of the acceleration of the block after it is released? /////
2nd example:
A 14 kg block is pushed up a ramp at a constant speed of 6.5 m/s. The ramp makes an angle of 25 degrees to the horizontal and the ramp is frictionless. The block is released and allowed to slide up the ramp until it stops. What is the magnitude of the acceleration of the block after it is released?
