Question

A car moving moving at a velocity of 54 km/h is stopped in 10s Find
it's acceleration

Sagar Kumar · Accepted Answer

Solution:u=54 km/h =54×518=15 m/sect=10 secv=0 m/secSince v=u +atOr, 0=15 +10aOr, a =-1510=-1
5 m/sec2 (negative sign shows that acceleration is in opposite direction to the motion of the car)
