An object of mass ? = 64 g slides on a frictionless table, constrained by a cord to a circular path of radius ? = 85 cm as shown below in top view. The object’s speed is a constant 40 cm/s. How much work is done by the tension force over half a revolution? (Answer in J.) The image illustrates a simple diagram of circular motion. It depicts an object with mass denoted by "m" moving in a circular path. The path is represented by a dashed circle. The radius of the circle is indicated by the line "r" extending from the center of the circle to the object on the perimeter. An arrow along the circle's path signifies the direction of the object's motion. This diagram is commonly used to explain concepts of centripetal force and acceleration in physics, where the object moves with constant speed along the circular path but continuously changes direction.

Question

An object of mass ? = 64 g slides on a frictionless table, constrained by a cord to a circular path of radius ? = 85 cm as shown below in top view. The object’s speed is a constant 40 cm/s. How much work is done by the tension force over half a revolution? (Answer in J.)

The image illustrates a simple diagram of circular motion. It depicts an object with mass denoted by "m" moving in a circular path. The path is represented by a dashed circle. The radius of the circle is indicated by the line "r" extending from the center of the circle to the object on the perimeter. An arrow along the circle's path signifies the direction of the object's motion. This diagram is commonly used to explain concepts of centripetal force and acceleration in physics, where the object moves with constant speed along the circular path but continuously changes direction.

Expert Solution

Step 1

Given data

The mass is $m = 64 g = 64 \times 10^{- 3} kg$

The radius is $r = 85 cm$

The speed is $v = 40 cm / s$

The diagram of motion of the mass m is as shown below,
