Constant Acceleration of a Car

What is the constant acceleration of a car that accelerates uniformly from rest to a speed of 55.0 mi/h in 10.0 s?

The constant acceleration of the car is 8.07 ft/s^2.

When a car accelerates uniformly from rest to a speed of 55.0 mi/h in 10.0 s, the constant acceleration of the car can be calculated using the formula:

acceleration = (v - u) / t

Where:

v = final velocity = 55.0 mi/h converted to 80.7 ft/s

u = initial velocity = 0 ft/s (since the car starts from rest)

t = time taken = 10.0 s

By substituting the values into the formula, we get:

acceleration = (80.7 ft/s - 0 ft/s) / 10.0 s

acceleration = 8.07 ft/s^2

Therefore, the constant acceleration of the car is 8.07 ft/s^2.
