Question

A car starts at rest and accelerates at a rate of 4 m/s^2. How far does the car travel in 5

Answer 1

Answer:

C. 50m

Explanation:

Given parameters:

Initial velocity  = 0m/s

Acceleration  = 4m/s²

Time of travel  = 5s

Unknown:

distance covered  = ?

Solution:

To solve this problem, we use the expression below;

   S  = ut  + $\frac{1}{2}$ at²  

S is the distance

u is the initial speed

t is the time

a is the acceleration

            S  = (0x 5) + $\frac{1}{2}$ x 4 x 5²   = 50m
