Answer 1

Answer #1

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 .

A 38.0-kg boy, riding a 1.50-kg skateboard at a velocity of 5.10 m/s across a level sidewalk, jumps forward to leap over a wall. Just after leaving contact with the board, the boy's velocity relative to the sidewalk is 6.00 m/s, 9.40° above the horizontal. Ignore any friction between the skateboard and the sidewalk. What is the skateboard's velocity relative to the sidewalk at this instant? Be sure to include the correct algebraic sign with your answer.

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.)
