The block shown in Figure 2 has mass m=7.0 kg and lies on a fixed smooth frictionless plane tilted at an angle θ = 22° to the horizontal. (a) Determine the acceleration of the block as it slides down the plane. (b) If the block starts from rest 12.0 m up the plane from its base, what will be the block’s speed when it reaches the bottom of the incline? (c) A block is given an initial speed of 4.5 ms-1 up the 22.0° plane. (i) How far up the plane will it go? (ii) How much time elapses before it returns to its starting point? Ignore friction.
