Which has more inertia, 20 cm3 of water or 10 cm3 of aluminum, and how many times more?
Answer to relevant QuestionsA 1.5-kg object moves up the y-axis at a constant speed. When it reaches the origin, the forces at 37o above the +x-axis, F2 = 2.5 N in the + x-direction, F3 = 3.5 N at 45o below the – x-axis, and F4 = 1.5 N in the – ...A gun is fired and a 50-g bullet is accelerated to a muzzle speed of 100 m/s. If the length of the gun barrel is 0.90 m, what is the magnitude of the accelerating force? (Assume the acceleration to be constant.) The engine of a 1.0-kg toy plane exerts a 15-N for-ward force. If the air exerts an 8.0-N resistive force on the plane, what is the magnitude of the acceleration of the plane? In Exercise 2, if the 35-N force acted downward at an angle of 40° relative to the horizontal, what would be the acceleration in this case? A lab notebook sits on a table 0.75 m above the floor. Your lab partner tells you the book has zero potential energy, and another student says it has 8.0 J of potential energy. Who is correct?
