A 920 kg block is pushed on the slope of a 30
frictionless inclined plane to give it an initial
speed of 50 cm/s along the slope when the block is 2.3 m from the bottom of the incline.
The acceleration of gravity is 9.8 m/s2 . What is the speed of the block at the bot-
tom of the plane?
Answer in units of m/s
