Question

A ball is thrown vertically upwards from a point P above the ground. It rises

to the highest point Q and returns to the same point P. What is the velocity and

the force acting on the ball at the highest point?​

Answer 1

Answer:

Answer is A.

If we know the initial velocity, from the equation, v

2

−u

2

=2as with s = h and v = 0 at the top of the path, initial velocity is given as 'u' and a = -g then:

h =

2g

u

2

.

Therefore, the maximum height reached =

2g

u
