a ball is projected from a table at 25m/s in a horizontal direction at the same time a second ball is projected off the table horizontally. How fast at the start does the second ball have to go off of the table to hit the ground at the same time as the first ball?
first ball has a mass of 20 n and the second ball has a mass of 10n. the size of the balls are the same.
Homework Answers
Second ball can be projected with any velocity horizontally it
will always hit the ground at the same time as the first
ball.
until it is given any vertical velocity.
As both balls have zero initial vertical velocity and equal
downward acceleration of gravity both ball will hit the ground at
the same time

Three balls are projected at the same speed from a cliff. Ball 1 is fired horizontally and hits the ground at t1. Ball 2 is fired at an angle of 30 degrees above the horizontal plane and hits the ground at t2. Ball 3 is fired at an angle of 60 degrees above the horizontal plane and hits the ground at t3. Which ball hit the ground from least to greatest. Which equation would you use to calculate the distance...

A ball is thrown with a purely horizontal velocity of 25m/s at a wall which is 15m away. The ball is thrown at a height of 1.6 m above the horizontal terrain. The ball has a coefficient of restitution of 0.75. After the ball impacts the wall and bounces off the wall back toward the thrower, how far from the wall will the ball initially strike the ground?

A stationary ball is let go from the top of a 75 cm long
diagonal table. It rolls down and off the edge, free falls and hits
the ground.
a) If it takes the ball 0,797 seconds to roll down the table
before it goes off the edge, what is it's average speed?
b) What is the balls speed when it goes off the edge? Formula for
even acceleration is Vm = (V0+V)/2
c) What is the horizontal speed of...

A ball is kicked with an initial velocity of 11 m/s in the horizontal direction and 21 m/s in the vertical direction. (Assume the bal is kicked from the ground.) (a) At what speed (in m/s) does the ball hit the ground? m/s (b) For how long (in s) does the ball remain in the air? (c) What maximum height (in m) is attained by the ball?

Liam throws a ball horizontally with a large force at a height of 1 m from the ground. At the same time, Lily drops another identical ball from the same height. Which of the two balls hits the ground first? The ball dropped by Lily Depends on the amount of force used by Liam. Neither - they both hit the ground at the same time. The ball thrown by Liam.
