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
