A particle is to move in an xy plane, clockwise around the origin as seen from the positive side of the z axis. In unit-vector notation, what torque acts on the particle if the magnitude of its angular momentum about the origin is (a) 4.0 kgm2/s, (b) 4.0t2 kgm2/s, (c) 4.02t kgm2/s, and (d) 4.0/t2 kg m2/s?
While sunbathing on the balcony of your 3rd floor apartment, you notice someone drop a m = 6.5 kg pumpkin from rest from the roof of the 5-story building across the street. Since you just completed a course on surveying, you know that the two identical buildings are d = 29 m apart, and have floors that are h = 4.8 m tall. The first floor is at ground level, as shown.
a) Determine the magnitude of the angular momentum of the pumpkin, in kgm^2/s, by you as it passes the fourth floor balcony of the other building.
b) Same question but with the 3rd floor, directly across from you.
c) Same question but as it passes the second floor.
d) Same question but immediately before it hits the ground.
I was not given the radius of the pumpkin so I need to find the magnitude of the angular momentums without r.
