43. A mother pushes her 120-newton child, who is
sitting on a swing. If the mother exerts a
10.-newton force on the child for 0.50 second,
wiat is the magnitude of the impulse imparted
to the child by the mother?
A) 5.0 Nos
B) 20. N/s
C) 60. Nos D ) 240 N/s
44 A 15-newton forca acto por 10

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

Option A

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,

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

the answer would be 32*f

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
