Question

An object has pi of 20 kg m/s and then pf of 30 kg m/s. If it took 2s, what is the force?

Answer 1

5N
Loook at what it says

Answer 2

5 N

Step-by-step explanation:

To calculate the force applied to the object, you can use the formula:

Force = (Final Momentum - Initial Momentum) / Time

Here, the initial momentum (pi) is 20 kg m/s, the final momentum (pf) is 30 kg m/s, and the time taken (t) is 2 seconds. Substituting these values in the formula, we get:

Force = (30 kg m/s - 20 kg m/s) / 2 s

Force = 10 kg m/s / 2 s

Force = 5 Newtons

Therefore, the force applied to the object is 5 Newtons.
