Question

What is the velocity (in ms) of a yos ko car initially moving at 25.5 m/s, just after it hits a 135 kg deer til running at 12.5ms in the same direction? Assume the deer remains on the car. Enter the magnitude.) Additional Materials Reading

Answer 1

→ Drawing the guven Scenario & Solving the problem. both start to move together U= 25.5m's U2 - 12.5 m/s lear - Ideer m2 = 135 kg m = 405 kg Cort deco m = m + m2= 905+135 m= 1040 Kg After collision) (Before collision) -> Assuming that car and clear collectively move with Velocity = V along the surface of ter collision. → Total linear momentum of system before collesi'on = Pi Pi- m, vir mauz - (905) (23:5) + (135)(125) ! Pi= 24765 kgm/s → Again total linear momentum of system after collision = Pz 1. P2= my - >> As we know that, during collisions the linear momentum in always conserved, 0) So, Pi=P2 » m v= 24765 kgm/s = 23.8125 mis 1 24765 24765 1040 m m - so the speed after collision = V = 23.8125 m/s
