Kindly help me out, Thank you.
A Golfer practising on a range
with an accelerated tree 4.9m above
the fairway is able to strike a ball
so that it leaves the club with a
horizontal velocity of 20m/s.
(Assume the acceleration due to
gravity is 9.8m/s^2 and the effect of air
resistance maybe ignored unless
othewise stated
1) How long after the ball leaves the
club will it land on the fairway?
2) What horizontal distance will the
ball travel before striking the fairway?
3) What is the acceleration of the ball
0.5s after being hit?
4) Calculate the speed of the ball
0.8s after it leaves the club?

A bullet of mass 1kg is fired and get
embedded into a block of wood of
mass 1kg initially at rest the velocity
of the bullet before collision is 90m/s
1) What is the velocity of the system
after collision?
2) Calculate the kinetic energy before
and after the collision.
3)How much energy is lost in collision?
