Three small metal balls are thrown at diffrent speeds off the top of a building to hit the ground 25m below. Sphere A is thrown directly downward at 10m/s while sphere B is dropped from rest. Sphere C is thrown upward at 5m/s. Calculate the time for each sphere to hit the ground below. Ball Time Unit impact A= B= C=

Two rocks are thrown simultaneously from the top of a very tall tower with identical speeds of v = 7.90 m/s, but in two different directions. (See figure.) One of them is thrown with an angle of 10.0 degrees below the horizontal, the other one at an angle of 50.0 degrees above the horizontal. How far will the rocks be from each other after 4.90 s? (Neglect air resistance and assume that the rocks will not hit the ground.)

Two golf balls are thrown simultaneously with the same initial speed from the edge of a cliff. One ball is thrown at an angle of 30° above the horizontal; the other is thrown horizontally. Neglect air resistance and rotation of the golf balls. Which statement below is correct? The golf balls strike the ground at the same time and with equal speeds. The golf balls strike the ground at the same time with different speeds. The golf balls strike the...

A ball is thrown horizontally from the top of a building hits the ground 0.25 s later, Ignore air resistance. If it had been thrown with twice the speed in the same direction, it would have hit the ground in: A) 0.40 s B) 0.50 s C) 1.00 s D) 0.25 s

A rock is thrown straight upwards from the top of the tower/ At the instant when the rock is released from the thrower's hand, the rock is 25m above the ground and moving straight upwards. Just before the rock crashes into the mud, it is moving straight downwards at 24.3 m/s. Assume air resistance is negligible. After the rock reached the muddy ground, the rock continued to move downwards, embedding itself .2m deep in the muddy ground before coming to...

Alex climbs to the top of a tall tree while his friend Gary waits on the ground below. Alex throws down a ball with an initial speed of 4.50 m/s from 56.0 m above the ground. The starting height of the ball thrown upward is 1.50 m above the ground. Ignore the effects of air resistance. 1) At what speed must Gary throw a ball up in order for the two balls to cross paths 28.0 m above the ground?...

Rock thrown off a cliff You want to know the height of a cliff so you throw a rock off the edge with an initial speed of 18.5 m/s inclined at an angle 30.3° above the horizontal. You have a friend that records that it takes 3.4 s for the rock to hit the bottom of the canyon after it is thrown. For the following questions, call up the positive y direction and make the positive x direction horizontal and...

1. Two identical eggs were thrown at the same time from the top of a building of height 100 m at a speed 20. One egg was thrown at an angle 40° above the horizontal while another was thrown at the same angle but below the horizontal. How long does it take for the other egg to hit the ground after the one of the eggs hits the ground? Does the time difference between the eggs hitting the ground depend...
