Unformatted text preview: motion with a force of 2,000 N. The truck accelerates at 2 m/s/s. What is the mass of the truck? F= ma A cheetah exerts a force of 600 N while running. If the cheetah has a mass of 30 kg, what is it’s acceleration? Weight=Force of gravity F g =mg • What is the force of gravity of a 20 kg stack of books? Normal Force The force perpendicular to the surface. • What is the normal force of the table on the stack of books? Out: A boat is sailing through the water with a force of 1250 N from the propeller and a mass of 300 kg. There is a resistance force of 650 N from the water. What is the acceleration of the boat?...

### 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.
