(18%) Problem 1: A student standing on a cliff throws a projectile from a vertical height d = 8.0 m above the level ground with velocity vo = 24.2 m/s at an angle 0 = 25 below the horizontal. It moves without air resistance. Use a Cartesian coordinate system with the origin at the projectile's initial position.

50% Part (a) With what speed, in meters per second, does the stone strike the ground? V = m/s

woes we stone strike the ground? DA 50% Part (b) If the projectile had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, then compare their impact velocities. More information is needed to conclude the relative strength of impact velocities. Grade Summary The impact velocities of the two situations will be the same Deductions Potential The impact velocity when throwing a stone above horizontal will be less than the case when throwing a stone below horizontal The impact velocity when throwing a stone above horizontal will be more than the case when throwing a stone below Submissions horizontal Attempts remaining 0 100%
