You are launching a 2-kg potato out of a potato cannon. The cannon is 1.5 m long and is aimed 30 degrees above the horizontal. It exerts a 50 N force on the potato. What is the kinetic energy of the potato as it leaves the muzzle of the potato cannon?

A 7.44-kg particle is subject to a net force that varies with position as shown in the figure. The particle starts from rest at x = 0. Fx (N) 3 2 2 4 6 8 10 12 14 16 What is its speed at the following positions? (a) x = 5.00 m 154.32 X Can you determine the kinetic energy of the particle at x = 5.00 m from the given graph? m/s (b) x = 10.0 m 154.33 x (m) X You appear to have added your result from part (a) to a speed calculated from the work done between 5 and 10 m. This doesn't work; you must calculate the work done over the entire 10 m distance. m/s (c) x = 15.0 m 151.31 X The force is positive throughout the entire interval. Does it make sense that the speed would decrease m/s
