From the top of a cliff, at a height of 45 m above the sea surface, a projectile is launched at an initial speed of 100 m / s, at an elevation angle of 60 degrees. After the projectile touches the surface of the water, it enters the sea experiencing a constant horizontal retardation of -25 m / s ^ 2 and a constant vertical retardation of -3 m / s ^ 2, both for a time of 2 sec, after of which, the projectile only descends with constant speed until it touches the sea floor. If the total time that the projectile was in motion is 25 seconds, determine the distance in a straight line between the projectile's point of departure and the point where it touches the sea floor.

A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 100m above ground level, and the ball is fired with initial horizontal speed v0=0. Assume acceleration due to gravity to be g = 9.80 m/s2. a)Assume that the cannon is fired at time t=0 and that the cannonball hits the ground at time tg. What is the y position of the cannonball at the time tg/2? b) Given that the projectile lands...

A ball rolls down from the top of an incline with a height of 5 m high without slipping. The ball has a diameter of 0.2m. What are the ball’s translational speeds a) at the center of the ball, b) at the contact point on the ground, and c) at the top of the ball when it arrives at the bottom? What values of "c" do you expect for hollow/solid balls? Will the hollow ball be faster?
