Answer:
Explanation:
given,
initial velocity of the ball = 20 m/s
angle of ramp = 22°
ball travel at a distance = 5 m
a) for friction less
v = 17.58 m/s
b) considering the friction
v = 17.16 m/s
Theoretically, if the objects have the same mass and are moving towards each other at a speed of 
, after a perfectly elastic collision, the object A is supposed to move with the same velocity in the opposite direction.
