Calculate the impulse when an average force of 10 N acts on a cart for 5.0 s.

To calculate: The impulse for a given average force exerted on a cart for a particular duration.
Answer to Problem 27A
The impulse on the cart is 50 kg−m/s
Explanation of Solution
Given:
An average force of 10 N is exerted on a cart for 5 s.
Formula used:
When a force F is applied on a body for a particular duration t, then it produces an impulse, expressed as,
Impulse=Ft
Calculation:
Here, an average force of 10 N is exerted on the cart for duration of 5 s. This gives an impulse of
Impulse=Ft=10×5=50 kg-m/s
Conclusion :
The impulse on the cart is 50 kg−m/s .
