Question

A car is travelling at a speed of 25 metre/second . After 10 seconds , it gets accelerated at a rate of 5 metre / second² . Find the distance travelled and the velocity after 10 seconds.

Answer 1

s=ut+1/2at^2
s=25*10+1/2*5*5*5
s=250+125/2
s=625/2
s=312.5m is distance travelled

v=u+at
v=25+5*5=50m/sec

Answer 2

u = 25 m/s

t = 10s

a = 5 m/s^2

s = ut + 1/2 at^2

s = 25 x 10 + 1/2 x 5 x 100

s = 500m

v = u+at

v= 25 + 5 x 10

v = 75 m/s
