Answer:
Explanation:
a) when the object is pulled up with velocity 2m/s, the system is in translation equilibrium,
therefore the total force acting upwards=total force acting downward
T=mg=50N
b) when the system is pulled up with acceleration a=2m/s²
T= F+mg=5(2) +5(10)
=60N

Explanation:
(a) When the object is pulled up with velocity 2m/s , the system is in translation equilibrium,
therefore the total force acting upwards = total force acting downward
T = mg = 50n
(b) When the system is pulled up with acceleration a= √2m/s
T=F+mg=5(2) + 5(10)
=60N.
