Question

20. A projectile is fired at 35$^\circ$ above the horizontal. Any effects due to air resistance are negligible. At the highest point in its trajectory, its speed is 20 m/s. The initial velocity had a horizontal component of (a) 0, (b) (20 m/s) $\cos$ 35$^\circ$, (c) (20 m/s) $\sin$ 35$^\circ$, (d) (20 m/s)/$\cos$ 35$^\circ$, (e) 20 m/s.
