Question

a bucket of mass 1.90 kg is whirled in a vertical circle of radius 1.45 m . at the lowest point of its motion the tension in the rope supporting the bucket is 29.0 n .

Answer 1

The speed of the bucket is v = 4.61 m/sec

For the free body diagram, and apply Newton's second law:

T - mg = m(v2/r)

Plug in known values,

25 - 1.00*g = 1.00(v2/1.40)

Solve for v,

v = 4.61 m/sec

What is motion?

Motion is  the change of position or direction of a body over time. Movement along a line or curve is called a translation. Movement that changes the direction of the body is called rotation. In both cases, all points on the body have the same speed (directional speed) and the same acceleration (time rate of change of speed). The most common motion combines both translation and rotation.

There are 6 types of motion

• Oscillatory Motion.

• Rotational Motion.

• Translational Motion.

• Periodic Motion.

• Circular Motion.

• Linear Motion.

• Uniform Motion.

• Non-Uniform Motion.
