Question

calculate the force required to impact a car,a velocity of 30m/s in 10 second. thhe mass of the car is 1500kg

Answer 1

Mass of the car = 1500 kg

Initial velocity (u) = 0 m/s

Final velocity (v) = 30 m/s

Time taken = 10 seconds

Acceleration (a) = $\frac{v - u }{t}$

a = $\frac{30 - 0}{10}$

$a = 3 \frac{m}{s^2}$

Force required = mass × acceleration

Force = 1500 × 3

Force = 4500 N

Hence, the force required to impact a car is 4500 N.
