The impulse of the cart is 18.2 kg-m/s
We are required to find the impulse on the cart
It is given to us that mass of cart is 13kg
It is also given that increase in speed is 1.4 m/s
We are required to find the impulse on the cart
Impulse :
Impulse of a body is defined as change in the momentum of the cart.
Impulse I = m(v-u)/t
Now (v-u)/t is the change in speed and it is given to us that there is increase in speed and hence it must be positive.
(v-u)/t = 1.4m/s
Therefore,
Impulse of cart is equal to its change in momentum:
Putting the value of mass in the equation, we get:
I = m(v-u)/t
= 13 x 1.4 = 18.2 kg-m/s
Therefore, the impulse of the cart is 18.2 kg-m/s
