A boy with a mass of 25 kg is sitting in a red wagon of mass 8.5 kg which is at rest. His friend begins pulling him forward, accelerating him with a constant force for 2.35 s to a speed of 1.8 m/s. Calculate the force with which the wagon was being pulled. 4.2 N

25.7 N

19.1 N

6.5 N

So, the force that given when the wagon was being pulled is approximately 19.1 N (C).

Hi ! For intermesso, this question will adopt a lot about the relationship of impulse to change in momentum. Impulse is the total force applied in a certain time interval. Impulses can cause a change of momentum, because momentum itself is a mass that is affected by the velocity of an object. We know that velocity is a vector quantity easy to change its direction. The relationship between impulse and change in momentum is formulated by :

With the following condition :

We know that :
