A ball is tossed so that it bounces off the ground, rises to aheight of 3.30 m, and then hits the ground again 1.30 m away fromthe first bounce.
a) how long is the ball in the air between bounces?
b)what is the balls velocity in the x direction?
c) what is the balls speed before the second bounce?
d) what is the angle of the velocity vector with respect to theground right after the first bounce?

A ball is tossed so that it bounces off the ground, rises to aheight of 2.90 m, and then hits the ground again 1.10 m away fromthe first bounce.

how long is the ball in the air between the two bounces?

** A steel ball of mass 5m slidesalong a frictionless surface and has its first elastic collisionwith a second steel ball of mass m. The second steel ball isattached to a half-meter-long string and is swinging backwardstowards the sliding ball. The collision occurs at the very bottomof the swinging massâs arc. Right before this first collision themagnitude of the velocity of the swinging ball is twice that of thesliding and their velocities point in opposite directions. Thecollision leaves the sliding mass motionless. The swinging massthen swings completely around with the minimum possible speed atthe top of the arc that keeps the string always taut. After acomplete revolution the masses then collide elastically again. Thesliding mass
ends up sliding to the right and the swinging mass swings back andforth. Use g = 10 m/s^2 and assume all surfaces arefrictionless.
(a) What is the speed the swinging mass immediately after the firstcollision?
(b) What speed must both of the masses have right before the firstcollision?
(c) What is the final speed of the sliding mass after the secondcollision?
(d) What maximum angle, from the vertical, does the swingingmass
obtain after the second collision
