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.

it is the second option.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
