Answer 2

Calculating Acceleration and Weight of the Load

To calculate the acceleration and weight of the load, we can use the given information about the speed and time it takes for the load to reach that speed.

Given: - Initial speed (u) = 0 m/s (as the load starts from rest) - Final speed (v) = 12 m/s - Time taken (t) = 8 seconds

Calculating Acceleration

The formula to calculate acceleration (a) is: a = (v - u) / t

Substituting the given values: a = (12 m/s - 0 m/s) / 8 s

a = 1.5 m/s²

Direction of Acceleration The acceleration is in the upward direction, as the load is being lifted vertically.

Calculating Weight of the Load

To calculate the weight of the load, we can use the formula: Weight = mass × acceleration due to gravity

However, the mass of the load is not provided in the given information. Without the mass of the load, we cannot calculate its weight.

In conclusion, the module of acceleration of the load is 1.5 m/s², and the acceleration is directed upward. The weight of the load cannot be calculated without the mass of the load.
