There is friction between the ramp and the block as it slides a distance x up theramp and then slides back down. The block then takes time tdown to slide back down to the bottom of the ramp, where it has speed Uf. This book basically caters to the needs of undergraduates and graduates physics students in the area of classical physics, specially Classical Mechanics and Electricity and Electromagnetism. A student strikes a block at the bottom of a ramp, giving it an initial speed v0 up the ramp, as shown. Point P is the highest point in the rock's trajectory, and point Q is level with the initial position of the rock. After the block reaches its highest point, it slides back down, but the magnitude of its acceleration is less on the descent than on the ascent.
