A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 19.8 m/s . A 1.0-kg stone is thrown from the basket with an initial velocity of 12.3 m/s perpendicular to the path of the descending balloon, as measured relative to a person at rest in the basket. That person sees the stone hit the ground 14.2 s after it was thrown. Assume that the balloon continues its downward descent with the same constant speed of...

1. A rock is dropped from a bridge that is 15 m above the surface of the river. How long does it take for the rock to hit the water? 2. A ball is thrown upward from the edge of the roof of a 20 m tall building with an initial velocity of 15 m/s. a) What is the maximum height reached by the ball? b) How much time does it take for the ball to reach the ground? c)...

A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 16.4 m/s . A 1.0-kg stone is thrown from the basket with an initial velocity of 19.0 m/sperpendicular to the path of the descending balloon, as measured relative to a person at rest in the basket. That person sees the stone hit the ground 17.3 s after it was thrown. Assume that the balloon continues its downward descent with the same constant speed of 16.4...

My A person standing at the top of a hemispherical rock of radius R 11.00 m kicks a ball (initially at rest on the top of the rock) to give it horizontal velocity v, as in the figure. (a) What must be its minimum initial speed if the ball is never to hit the rock after it is kicked? m/s (b) With this initial speed, how far from the base of the rock does the ball hit the ground? Need...
An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground.
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...
