Question

a sports event, the car starts from rest, in 5.0 s its acceleration is 5.0 m/s2.
culate the distance travelled by car.
​

Answer 1

Answer:

62.5m

Explanation:

Given parameters:

Time  = 5s

Acceleration  = 5m/s²

Unknown:

Distance traveled by car  = ?

Solution:

To solve this problem, we use one of the motion equations as given below:

     S  = ut + $\frac{1}{2}$ at²

S is the distance traveled

t is the time taken

u is the initial velocity  = 0m/s

a is the acceleration

Now insert the parameters and solve;

      S = (0 x 5) + ($\frac{1}{2}$ x 5 x 5²) = 62.5m
