Two blocks are at rest on either side of a spring. What is the total (net) momentum of the two-object system after the expansion of the spring?
0 Kg m/s
What factors affect an object's momentum?
Mass and Velocity
m1v1i+m2v2i = m1v1f+ m2v2f
Elastic
Mario travels at 2 m/s and hits Luigi's identical cart that is initially at rest. After the collision Mario transfers all of his momentum to Luigi. Which graph best represents Mario's velocity before and after the collision.
D
Two objects of different mass falling from the same height would have a difference in which of these properties:
Acceleration / Distance / Velocity / Momentum
Momentum only
m1v1i+m2v2i = (m1 + m2)vf
Inelastic
A 60 kg physics student at rest on a frictionless ice skating rink throws a 5 kg box, giving the box a velocity of 4 m/s. What is the velocity of the student immediately after the box is thrown?
-0.33 m/s
If you had a normal force of 660 N while running at 7 m/s, what is your momentum?
462 Kg m/s
Give the Explostion equation:
(m1 + m2)vf = m1v1i+m2v2i
A 2 kg snowboard is sliding along some frictionless ice at a velocity of 7 m/s. A 59 kg snowboarder then jumps on the board at 0.5 m/s. What is the final velocity of the snowboarder and their board?
0.7 m/s
The accompanying velocity-time graph represents the motion of a 10 kilogram cart along a straight line. Calculate the change in momentum of the cart from t= 3s and t = 6 seconds.
