Questions
A 500 kg rоcket sled is sitting аt rest аt the bоttоm of а 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. a) Find the height of the ramp. height = [rampheight] 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 = [xcomponent] + [ycomponent] c) What is the thrust provided by the rocket engine? Thrust = [thrustforce] d) What is the total time the sled is in the air? Time of Flight = [flighttime] e) When the sled lands, how far has it traveled horizontally from the end of the ramp? xdistance = [horizontaldistance]
