Question

A 105 kg fullback is running at3.3 m/s to the east and is stopped in0.75 s by a head-on tackle by a tackler running due west. 1a Calculate the original momentum of the fullback b. Calculate the impulse exerted on the fullback c.Calculate the impulse exerted on the tackler d. Calculate the average force exerted on the tackler A 105 kg fullback is running at3.3 m/s to the east and is stopped in0.75 s by a head-on tackle by a tackler running due west. 1a Calculate the original momentum of the fullback b. Calculate the impulse exerted on the fullback c.Calculate the impulse exerted on the tackler d. Calculate the average force exerted on the tackler

Explanation / Answer

Given :              Mass (m) = 105 kg              Initial velocity (v1) = 3.3 m /s              Final velocity (v2)   = 0 (a)       Original momentum is : mv   = 105 * 3.3   = 346.5 kg- m /s (b)      Impulse is :                   J =   m (v2 - v1 ) = 105 (0 - 3.3 ) = 346.5 kg - m /s           It is also equal to  impulse exerted on thetackler. (d)         Average force:                     F =    m (v2 - v1 ) / t  = 346.5 / 0.75                                                            = 462 N Hope this helps u!
