Stunt Driver's Car Cliff Jump Calculation

a) How long did it take for the stunt driver's car to reach the water after jumping off the cliff? a) It took the stunt driver's car 3.33 seconds to reach the water after jumping off the cliff.

In this scenario, the stunt driver drove the car off a cliff with an initial velocity of 15 m/s, and the surface of the water was 25 m below the cliff. To calculate the time it took for the car to reach the water, we can use the equation of motion:

S = (v + u) / 2 * t

Given that the initial velocity u = 15 m/s and the height S = 25 m, we can substitute the values into the equation:

25 = (0 + 15) / 2 * t

25 = 7.5t

t = 25 / 7.5

t = 3.33 seconds

Therefore, it took the car 3.33 seconds to reach the water after jumping off the cliff.
