I am unable to see the perfect question

I am answering this with the values i am able to see

It is given that velocity at highest point is half the initial velocity.

Velocity at highest point is given by

V=ucos(theta)

As given

V=1/2U

Hence,

ucos(theta)=1/2u

Cos(theta)=1/2

Theta=60

Max range =u²sin2(theta)/g

Substitute value of theta we get

Range =√3u/2g

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
