A 0.55 kg block of ice is sliding by you on a very slippery floor at 3.5 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.0025 seconds. The block eventually slides at an angle of 28 degrees from its original direction (labelled theta in the diagram). The overhead view shown in the diagram is approximately to scale. The arrow represents the average force your toe applies briefly to the block of ice.
What is the unit vector in the direction of the block's momentum after the kick?
What is the x-component of the block's momentum after the kick
What is the magnitude of the block's momentum after the kick?
find the z-component of the block's momentum after the kick
What was the magnitude of the average force you applied to the block?
momentum = (mass)(velocity)
change in momentum = Fnet(time)
The Attempt at a Solution
I honestly have no clue what do do for this particular question. For example, what do I use the given angle (28 degrees) for?
This is how I tried the question:
First multiply the mass of the the block by the speed (0.55 x 3.5)
This will yield the momentum of the block
I don't know where to proceed beyond this point.
I need to find the momentum of the block after the kick. How do I do this? I only know the duration for which the contact occured?
All help will be greatly appreciated.
