Understanding Tension and Time in Lifting a Metal Box
Tension Calculation:
Tension (T) = Weight (W) + mass (m) x acceleration (a)
Given:
Weight of the box (W) = 50 kg
Acceleration (a) = 0.8 m/seg2
Weight (W) = mass (m) x gravity (g)
Substitute the values:
T = 50 x (9.8 + 0.8)
T = 530 N
Time Calculation:
Time (t) = Square root of (2 x height (y) / acceleration (a))
Given:
Height (y) = 10 meters
Substitute the values:
t = Square root of (2 x 10 / 0.8)
t = 12.65 seconds
