T = tension force in the rope in upward direction
m = mass of the box attached at end of rope = 56 kg
W = weight of the box in downward direction due to gravity
a = acceleration of the box in upward direction = 5.10 m/s²
weight of the box is given as
W = mg
inserting the values
W = (56) (9.8)
W = 548.8 N
force equation for the motion of the box is given as
T - W = ma
T - 548.8 = (56) (5.10)
T = 834.4 N
Answer:
15 J
Explanation:
Work = Force x Distance
15= 30 x 0.5
