Acceleration = resultant force ÷ mass = 10.5 million ÷ 2 million = 5.25 m/s 2. Comparing accelerations. The acceleration of the model rocket at 90 m/s 2 is far greater than the Space Shuttle at 5.25 m/s 2, but there is a significant difference in the motion after launch. Firstly, the model rocket only had enough propellant for 1 second of thrust.
The acceleration of the block is a1. Express all algebraic answers in terms of m, F 1, θ, a 1, and fundamental constants. a. On the figure below, draw and label a free-body diagram showing all the forces on the block. b. Derive an expression for the normal force exerted by the surface on the block. c.
