A projectile is launched from the top of a 75m-tall cliff with an initial velocity of 31m/s at an angle of 42° above the horizontal. For this problem, assume that the base of the cliff is at y 0 and that the projectile starts at x 0 on a standard xy plane 1. What is the maximum height above the ground that the projectile will achieve? 2. How long will it take for the projectile to reach its maximum height?...

A ball is launched from a cliff that is 20.0 m above the surface of a very deep lake. SEE FIGURE. The initial speed is |v_1| = 40.0 m/s. The ball follows the one-dimensional trajectory schematically shown. Assume the magnitude of gravitational acceleration is g = 9.80 m/s^2. Neglect air resistance. The ball hits the water surface and moves downward toward the bottom of the lake with an UPWARD acceleration whose magnitude is |a| = 3.00 m/^2. (Scales shown in...

Ali and Steven walk up a mountain and drop a ball from the edge of a cliff. The height of the ball can be modelled by the function h(t) = -5t2 + 80 where h(t) is the height of the ball above sea level, in metres, at time t seconds after it is dropped.b) Determine the equation for h-1(t).
