Paul’s 10 kg baby sister susan sits on a mat. paul pulls the mat across the floor using a rope that is angled 30° above the floor. the tension is a constant 30 n and the coefficient of kinetic friction is 0.20. use work and energy to find susan’s speed after being pulled 3.0 m.

The speed of Susan is 2.37 m/s

Explanation:

To visualize better this problem, we need to draw a free body diagram.

the work is defined as:

here we have the work done by Paul and the friction force, so:

Now the change of energy is:

speed= 1.95866m/s ~= 2.0 m/s

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

the following is queen elizabeth’s purposes:
