The same
How can a 1 kg soccer ball have a momentum equal to a 8 kg bowling ball?
Soccer ball moves same speed as bowling ball
Soccer ball moves 8 times faster than the bowling ball
Soccer ball moves 8 times slower than the bowling ball
Bowling ball must be stationary
Why does pulling a sling shot back further give a greater change in momentum?
Larger force acted over a longer time
Larger force acted over a shorter time
Larger force acted over the same time
Smaller force acted over a shorter time
Why is hitting a hay stack and coming to a stop better than hitting a brick wall and coming to a stop
Larger force acted over a longer time
Larger force acted over a shorter time
Larger force acted over the same time
Smaller force acted over a shorter time
Small force acted over a long time
What are the units of Impulse?
kgm/ss
kg/s
m/s
kgm/s
Imps
A ping-pong ball moving east at a speed of 4 m/s, collides with a stationary bowling ball. The ping-pong ball bounces back to the west, and the bowling ball moves very slowly to the east. Which object experiences the greater magnitude impulse during the collision?
the ping-pong ball
the bowling ball
Neither; both experience the same magnitude impulse
It’s impossible to tell since the velocities after the collision are unknown

50 kgm/s
10 kgm/s

will double
will half
will quadruple (x4)
will be quartered (x 1/4)
