In a crash test, a car is driven into a solid wall at a speed of 35 mph.(Figure 1) shows the car's acceleration as it crashes into the wall.

Part A

What is the maximum force experienced by the 1650kg car?

Express your answer with the appropriate units.

Fmax = Figure

1 of 1

a (m/s) 300 200 100 0 t (ms) 0 50 100 150 200

Given that,

v = 35 mph

m = 1650 kg

amax = 300 m/s^2 (from the graph)

Maximum force experienced by car,

Fmax = m * amax

Fmax = 1650 * 300

Fmax = 495000 N
