Explanation:
Impulse-Momentum relation:


We solve the equations in order to find the braking force:

Take breaks and drink plenty of water not to much because it will make you sick sorry apparently pu ke is a bad word.
given:
mass = 5000 kg
u (initial velocity) = 0 m/s
v (final velocity) = 70 m/s
time taken to change velocity = 3600 s
acceleration = v - u / t
a = 70 - 0 / 3600
a = 70 / 3600
a = 0.0194 m/s2 (approx)
given: mass = 5000 kg
acceleration = 0.0194 (found in 1st part)
force = mass * acceleration
f = ma
f = 5000*0.0194 = 97 N
therefore the acceleration will be 0.0194 m/s2
and the force involved in acceleration will be 97 N
A large amount of molten magnetic material containing Iron is believed to rotate (as a liquid) in the Earth’s core.
