![]() Determine the final velocity of the object. A resistive force of 6.0 N then impedes its motion for 8.0 seconds. s impulse acts upon it in the direction of motion for 5.0 seconds.A 4.0-kg object has a forward momentum of 20. So if impulse is known and time is known, force can be easily determined.į = Impulse/t = (-16.7 N s) / (0.100 s) = -167 Nĥ8. ![]() (b) The impulse is the product of force and time. Where the "-" indicates that the impulse was opposite the original direction of motion. (a) determine the impulse with the wall, (b) determine the force of the wall on the ball.Īnswer: Answer: (a) -16.7 N s (b) -167 N A 0.530-kg basketball hits a wall head-on with a forward speed of 18.0 m/s.
