Problem 46P

Problem 46P

Susan’s 10 kg baby brother Paul sits on a mat. Susan 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 friction is 0.20. Use work and energy to find Paul’s speed after being pulled 3.0 m.

Step-by-Step Solution:

Solution 46 P

Step 1 of 3

We have to find the speed of Paul’s after being pulled for 3.0 m.

The free body diagram for the problem is as shown in the below figure.

The normal force acting on Paul in the direction can be found from Newton’s second law.

Where,

tension in the rope = 30 N

in N

kg

m/s2

Thus,
