A 500 kg rocket sled is sitting at rest at the bottom of a ramp (i.e., ground level, y = 0 m). It has just enough fuel to accelerate along the length of the ramp. The sled is propelled along a 25 m long ramp of angle θ = 30˚ with a constant acceleration. When it leaves the ramp, the engine cuts off and it has a speed of 948.7 m/s. Once the sled leaves the ramp, it travels as a projectile through the air. (25 points) a) Find the height of the ramp. height = b) Find the velocity vector of the sled at the instant it leave the ramp. Give the velocity in terms of the x- and y- coordinate system shown. v = + c) What is the thrust provided by the rocket engine? Thrust = d) What is the total time the sled is in the air? Time of Flight = e) When the sled lands, how far has it traveled horizontally from the end of the ramp? xdistance =
