A soccer ball would keep moving forever without physics, because without force to act upon the soccer ball, it could, or will not be able to stop the acceleration. And force is a factor in physics.
U need to set up n solve the general eqn for simple harmonic motion:
x" = -(k/m)x
solution is x(t) = (x0)*cos(wt) + (v0/w)*sin(wt)
where w=sqrt(k/m), x0 is x-position at t=0 and v0 is vel at t=0
u already calculated f in Q.2 and w = 2*pi*f
x0 is 0 as it starts at eqm
v0 is given at 5.1
so u have x(t)
vel is given by x'(t) = (x0)*(-w)*sin(wt) + (v0/w)*w*cos(wt)
substitute t=0.32, x0=0, v0=5.1 n w in the above, u can solve for v at t=0.32.
The given statement "If you see fire or smoke coming from your vehicle's hood, you should pull over and get away from the vehicle as soon as possible." is True.
What to do when there is smoking engine in your car?
You should take rapid action if the smoke seems to be coming from a fire under your bonnet.
- Don't try to prop the bonnet open; instead, pull the bonnet release lever.
- Remove everyone from the vehicle and maintain your distance.
- Ask for the fire service by dialing 999.
- If it is safe to do so, warn oncoming traffic.

Answer:20s
To find speed we have to divide speed and distance
5=100/?
100/5=20
