Question

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

Answer 1

Speed after 10 sec is 7 m/s and distance travelled is 60m

Answer 2

Hello,

The initial velocity of the motorcycle = 5m/sec

Acceleration = 0.2 m/sec²

Time =10 seconds

From the equations of the motion we know that
✔️ v = u+at

So,
V = 5 + 0.2 *10 = 5+2 =7 m/sec

So, the final velocity of the object is 7 m/sec

Now,
Again we know that
✔️2as = v²-u²
So, s= v²-u²/2a
So,s= 49 - 25 /0.4 = 24/0.4 =60 m

Therefore, The distance travelled is 60 m

Hope this will be helping you
