A tennis ball is thrown vertically upward with an initial velocity of +8.0 m/s. (a) what will the ball's speed be when it returns to its starting point? (b) how long will the ball take to reach its starting point? 6) 1. A ball is projected horizontally from the top of a 92m high cliff with an initial speed of 19.8m/s. Determine a)horizontal displacement, b) Final speed before hitting the ground

----------> (I must show all work)A tennis ball is thrown upward at an angle from point A. It follows a parabolic trajectory and hits the ground at point D. At the instant shown, the ball is at pointB. Point C represents the highest position of the ball above the ground.While in flight, how do the x and y components of the velocity vector of the ball compare at the points A and D?A) The velocity components are non-zero at A...

Can anyone explains all the answers? Two balls, A and B are thrown at the same angle above horizontal, but initial velocity of ball A is two times greater than initial velocity of ball B. Ignore air resistance. we can conclude that horizontal range covered by ball A is same as range covered by ball B twice the range covered by ball B four times the range covered by ball B. greater than horizontal range covered by ball b, but...

What is faster, up or down? A ball of dough ?? = 1 kg is thrown vertically upwards from the surface of the Earth, with a positive initial velocity ??0 = 20 m / s. Suppose the forces acting on the ball are gravity and a retarder of air resistance, with opposite direction to that of the movement. 2._ If the retarding force is proportional to the instantaneous velocity, use the second law of Newton to determine an equation that...

(1 point) A stone is thrown from a rooftop at time t 0 seconds. Its position at time t (the components are measured in meters) is given by r()-бі-50+ (24.5-49:2) k. The origin is at the base of the bulding, which is standing on flat ground. Distance is measured in meters. The vector i points east,j points north, and k points up. (a) How high is the rooftop? meters. (b) When does the stone hit the ground? seconds (c) Where...
