In Problems through you are given the equation(s) used to solve a problem. For each of these, you are to
a. Write a realistic problem for which this is the correct equation(s).
b. Draw a pictorial representation.
c. Finish the solution of the problem
a. A toy car is used to move the block with mass is 2.0kg at rest, the velocity of the block on frictional surface of length is 4.0 m/s The coefficient of kinetic friction is 0.15
b. The pictorial presentation is as follow:
c. The tension in the string is
Inertia is a fundamental feature of all matter, and mass is a quantitative measure of it. A force is a push or pull on an object caused by the interaction of the thing with another object.
A toy car is used to move the block with
mass is at rest,
the velocity of the block on frictional surface of length is .
The coefficient of kinetic friction is
The pictorial presentation is
Let T be the tension in string,
We are given,
Solve for T
The left end of a spring is attached to a wall. When Bob pulls on the right end with a 200 N force, he stretches the spring by 20 cm. The same spring is then used for a tug-of-war between Bob and Carlos. Each pulls on his end of the spring with a 200 N force.
How far does the spring stretch? Explain.
