A ball is dropped from the top of a building 100 m high. (Ignore air resistance) a) How long does it take the ball to hit the ground? b) What is the speed of the ball when it hits the ground?
A 3.00 kg ball is dropped from the roof of a building 176.4 m high. While the ball is falling to Earth, a horizontal wind exerts a constant force of 12.0 N on it. a.)How far from the building does the ball hit the ground? b.)How long does it take to hit the ground? c.)What is its speed when it hits the ground?
A ball is dropped from the top of a 68 m building. How long does it take for the ball to hit the ground? In the previous problem, what is the speed of the object the instant before it hits the ground?
A ball is dropped from the top of a cliff. the height of the cliff is 1000m. a) how long does for the ball to hit the ground if the cliff is on earth (g= 9.80 m/s^2)? b) how long does it take if its on the moon (g= 1.60 m/s^2)?
A balloon filled with water is dropped from a height of 20.0 m. At the same time, a dart is fired straight up from the ground below the balloon. The initial speed of the dart is 15.0 m/s. When does the dart hit the balloon and how high above the ground does the dart hit the balloon? Assuming that the balloon breaks instantaneously and that the dart doesn’t affect the motion of the water, how long after the balloon breaks...
