-1/4
Solve for j and Tj than you have
-j=4Tj
4T=-j/j
4T=-1
T=-1/4

Answer
given,
radius of merry - go - round = 4 m
mass of the disk = 120 kg
speed of the merry- go-round = 0 rad/s
speed = 2 m/s
mass of student = 60 kg
initial angular momentum of the system
final angular momentum of the system
from conservation of angular momentum
now,
change in kinetic energy of the system
initially the merry-go-round was on rest KE_i = 0
Answer:
Explanation:
You don't do the same amount of work. The work formula is F*d = W
W = work
F = force
d = the distance moved.
So you do more work when you move the 10N object because the Force (F) has doubled.
