Chapter 8, Problem 27A

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

To determine

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 $50\text{kg}-\text{m/s}$

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,

  $\text{Impulse}=Ft$

Calculation:

Here, an average force of 10 N is exerted on the cart for duration of 5 s. This gives an impulse of

  $\begin{array}{c}\text{Impulse}=Ft\\ =10\times 5\\ =\text{50 kg-m/s }\end{array}$

Conclusion :

The impulse on the cart is $50\text{kg}-\text{m/s}$ .
