Acar of m = 1200. kg collides with a tree while traveling 60.oo mph. the collision occurs over a time perido of 0.0500 seconds. determined the margnitude of the force exerted on the car as it comes to rest during the collision (1 m/s= 2.24 mph

Force exerted on the car,

Explanation:

It is given that,

Mass of the car, m = 1200 kg

Initial velocity of car, u = 60 mph = 26.8224 m/s

Time of collision, t = 0.05 s

We need to find the  magnitude of the force exerted on the car as it comes to rest during the collision (final velocity = 0)

We know that,

impulse = change in momentum

F = -643737.6

or

So, the magnitude of force exerted on the car is . Hence, this is the required solution.
