Kinematics
a car starts from rest and reaches a speed of 80 ft/s after traveling 500 ft along a straight road.
determine its constant acceleration and the time of travel.

The acceleration and time are 1.95 m/s and 12.5 s.

Explanation:

Given that,

Speed = 80 ft/s =24.384 m/s

Distance = 500 ft =152.4 m

We need to calculate the acceleration

Using third equation of motion

Where, u = initial velocity

v = final velocity

a = acceleration

s = distance

Put the value in the equation

We need to calculate the time

Using first equation of motion

Hence, The acceleration and time are 1.95 m/s and 12.5 s.

as technology advances, new experiments often expose problems in accepted theories. c
