5.0 N.s ( 5.0 newton second) is the magnitude of the impulse imparted to the child by the mother

Option A

Step-by-step explanation:

An impulse is a variation in the object's momentum when the object is subjected to force for a time period. Therefore, you can use the pulse to calculate the change in pulse or use the pulse to calculate the average impact force. The equation for impulse is given by,


J= Force * time

Given data:

F = 10 N

t = 0.50 s

We need to find the magnitude of the impulse. By applying the given values to the above equation, we get


J = 10 * 0.5=5.0\ \mathrm{N} .\mathrm{s}
