A student pulls down with a force of 40 N on a rope that winds around a pulley of radius 5 cm. find the torque?

2N

Explanation:

Given that a student pulls down with a force of 40 N on a rope that winds around a pulley of radius 5 cm. find the torque?

Solution

Using the formula

Torque = Force × radius

I.e

Torque = F r

Where

F = 40N

r = 5 cm = 5/100 = 0.05m

Substitute all the parameters into the formula

Torque = 40 × 0.05

Torque = 2 N

Therefore, the torque on this scenario is 2 N

think its the third option

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
