A motorcycle moving with a speed of 5 m/s is subjected to an acceleration of 0.2 m/s2. Calculate the speed of the motorcycle after 10 seconds, and the distance travelled in this time.

Answer :

According to the Question,

u = 5m/s

a = 0.2 m/s2

t = 10 sec

v= ?

s=?

We know that v= u+at, Putting the values in the equation,we get:-

v= 5+(0.2)x10

v= 7 m/s

We know that v2-u2= 2as, Putting the values in the equation, we get:-

(7)2-(5)2= 2x(0.2)x s

49-25= 0.4s

s =
