b. 100.
c. 10.
d. 1000.
the main difference between speed and velocity involves
a. gravity.
b. direction.
c. distance.
d. weight.

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
