(a(i))[2]
Determine $F_1$.
(a(ii))[2]
Use Fig. 3.1 to demonstrate that, for a compression of $0.045\,\text{m}$, the spring’s elastic potential energy is $0.81\,\text{J}$.
(b(i))[1]
The toy changes the spring’s elastic potential energy into the ball’s kinetic energy. Use the information in (a)(ii) to work out the percentage efficiency of this change.
(b(ii))[3]
Determine the initial momentum of the ball as it leaves the toy.
(c(i))[2]
Calculate $h$.
(c(ii))[2]
Determine the average force from air resistance acting on the ball during its motion from A to B.
(c(iii))[1]
When air resistance acts, the ball takes time $T$ to travel from A to B. State and explain whether the time taken for the ball to travel from A to its maximum height will be more than, less than or equal to time $T$ if air resistance is absent.
