Name______________________________________ Newton’s Second Law Problems- Introduction 1)  a)  A force of 50 N acts on a 5 kg object.    If the object is initially at rest, and the   force acts for 10 seconds, determine the final velocity of the object. 2)  A particular rocket’s engine can supply 200 N of propulsive force.  If the rocket has a      mass of 10 kg, find the acceleration of the rocket if it is fired straight up.    3)  Two forces are acting concurrently on a 25 kg cart.  The first force has a magnitude of         30 N and is directed due north.  The second force has a magnitude of 25 N and is       directed due east.  Find the acceleration (magnitude and direction) of the cart?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
