Question

a stunt driver is supposed to drive her car through the wall of a bank building. The stunt driver is traveling at 40m/s when she hits the wall. when her car exits the wall, she slowed down to 35m/s. it takes the driver 0.12 sec to travel through the wall. calculate the acceleration

Answer 1

The acceleration of the car is approximately -41.67 m/s².

Step-by-step explanation:

To calculate the acceleration, we can use the equation:

acceleration = (final velocity - initial velocity) / time

Given that the initial velocity is 40 m/s, the final velocity is 35 m/s, and the time is 0.12 s, we can substitute these values into the equation:

acceleration = (35 m/s - 40 m/s) / 0.12 s = -41.67 m/s²

Therefore, the acceleration of the car is approximately -41.67 m/s².
