Q 7.31: A football player with a mass of 110 kg runs into a stationary tackling sled that has a mass of 250 kg. Both the play

science physics

Answer 1

Answer #1

motion after jumping into the sled

u mg d = 0.5 m v^2

0.5* 9.8* 0.25 = 0.5* v^2

v = 1.565 m/s

using conservation of momentum

m1 v1 = (m1 + m2) v

110* v1 = ( 110 + 250) * 1.565

v1 = 5.1 m/s

Answer 2

Two football players collide head-on in midair while chasing a pass. The first player has a 110 kg mass and an initial velocity of 4.10 m/s in the positive x direction, while the second player has a 125 kg mass and initial velocity of 3.40 m/s in the negative x direction. What is the x component of their velocity just after impact if they cling together? (Indicate the direction with the sign of your answer.)
