3. A projectile is launched with initial velocity V and angle 45° with horizontal. The initial coordinate of the projectile is (0, 0). If the maximum height reached by the projectile is 100 m, what was the initial velocity (m/s)? 4 (Figure A). Determine the velocity of the 5 kg block under the action of the force shown at t = 5 s, if v = 0 at t = 0. The surface is frictionless. Draw the free-body diagram of the block. F = (201) N
