Question

If a car travels 50 m distance in 4 s with a acceleration of 5m/s² , then what was it's initial speed?

Open in App

Solution

Using first law of equation formula
s=ut+1/2at²
Given data is
S=50
t=4sec
a=5m/s²
Putting the values in above formula
50=ux4+1/2x5x16
50=4u+40
4u=10
u=10/4=2.5m/s²
