Solution) m1 = 48 kg
m2 = 2 kg
u1 = u2 = 1.20 m/s
V = ?
Applying conservation of momentum
(m1)(u1) + (m2)(u2) = (m1)(V1) + (m2)(V2)
(48)(1.20) + (2)(1.20) = (48)(V1) + (2)(0)
=> 60 = (48)(V1)
= > (V1) = (60)/(48) = 1.25 m/s
V1 = 1.25 m/s
Option(4) 1.25 m/s in the same direction as he was riding .

Dan is gliding on his skateboard at 2.36 m/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 8.02 m/s (as measured by an observer on the ground). Dan's mass is 60.1 kg and the skateboard's mass is 4.79 kg . If the jump requires 0.122 s to complete, what average force did the skateboard exert on dan?

-A werewolf of mass (m1=15 kg) naps atop a skateboard of mass (m2=5 kg) that is lying at rest precariously close to the edge of the Grand Canyon. Suddenly, a vampire of mass (m3=2 kg) emerges from the bushes and runs towards the napping werewolf with a constant speed of (v=10.8 m/s). Letting the direction of the running vampire's inital velocity be the positive direction, what is the running vampire's initial momentum? (Give your answer to 3 sig figs. and...

2. A 67 kg Samer is jogging down the street at a modest 8.2 m/s when he sees a 2 kg skateboard rolling in the same direction that he is running, just ahead of him. He could see that the skateboard was rolling with a constant velocity of 0.4m/s and decided to jump horizontally onto the top it. When he jumps onto the skateboard, Samer sticks without slipping, and the collision takes 0.15s. After the collision, the Samer-skateboard system continue...

A girl on a skateboard (total mass of 40 kg) is moving at a speed of 15 m/s at the bottom of a long ramp. The ramp is inclined at 18° with respect to the horizontal. If she travels 13.4 m upward along the ramp before stopping, what is the net frictional force (in N) on her? (Assume the positive direction is upward along the ramp. Indicate the direction with the sign of your answer.)
