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.
