New Problems reloads the page with new variable values in all questions. You must do this after grading the test to rework it another time.
Make sure to enter your answers in the specified units .
1
A bullet with a mass of g strikes a fixed block at a speed of m/s. The bullet stops after penetrating cm into the block. What is the magnitude (in N) of the average net force acting on the bullet?

2
A wagon with a mass of kg is accelerating at 1.5 m/s2. The wagon is being pulled by its handle which makes an angle of º to the ground, and there is a frictional force of N. What is the force acting on the handle?

3
Two forces, N and N, º apart are acting on a 5.00 kg object. What is the magnitude (in m/s2) of the object's acceleration?

4
How many degrees from the larger force is the acceleration of the object in the previous question?

5
A cart is placed on a ramp sloped at º to the horizontal. What is the cart's acceleration (in m/s2) if friction is negligible?

6
A skier starting from rest descends a º slope. If the coefficient of friction is , what is the skier's speed (in m/s) after seconds?


Once you have submitted your answers for grading by clicking the grade button, you cannot resubmit answers for the same Problem Set--you must use the 'New Problems' button first.
