Answer:
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.
