Question

A 7 kg block measures 8 cm by 12 cm by 24 cm. When it slides on a 12 cm by 24 cm face, it moves with constant speed when pulled horizontally by a force whose magnitude is 12 N. How big a horizontal force must be applied to pull it with constant speed if it slides on a 8 cm by 24 cm face?

Step 1

The weight (W) of the block can be calculated using the formula: \[ W = m \cdot g \] where \( m = 7 \, \text{kg} \) (mass of the block) and \( g = 9.81 \, \text{m/s}^2 \) (acceleration due to gravity). \[ W = 7 \, \text{kg} \cdot 9.81 \, \text{m/s}^2 = Show more…
