How much times is required for this heater to raise the temperA 100g granite cube slides down a frictionless 38 degreeincline. At the bottom, just after it exits onto a horizontaltable, the granite collides with a 250g steel cube at rest. How high above the table should the granite cube be released to givethe steel cube a speed of 170cm/s? (Answer in cm)
