Question

what is the acceleration of a car moving in a straight line path that increases its speed from zero to 100km/h in 10 seconds

Answer 1

Since initial velocity is 0 km/hr and final velocity is 100km/hr .so 100km/hr= (250/9)m/s. Now we know acceleration= (final velocity-initial velocity)/time . So ,a= (250/9)/10.so a= 25/9 m/s
