two cars weighing 1500kg are made to collide with a wall. The initial and final velocities of the car are-15.0m/s and 2.6m/s. respectively. If the collision lasts for 0.15s,then find the impulsive force exerted on the car

Answer:
Force = mass × Acceleration
Acceleration = change in speed ÷ change in time
Change in speed is : 2.6 - 15 = - 12.4m/s
t = 0.15
a = 12.4/0.15 = - 82.67m/s²
The negative sign indicates that car decelerates.
F = 1500 × 82.67 = 24005 N

Answer:
F=ma
a=v/t
Explanation:
Change in speed is : 2.6 - 15 = - 12.4m/s
t = 0.15
a = 12.4/0.15 = - 82.67m/s²
The negative sign indicates that car decelerates.
F = 1500 × 82.67 = 24005 N
