Question

The mass of the helicopter is 9300 kg. It takes off vertically at time t = 0. The pilot advances the throttle so that the upward thrust of its engine (in kN) is given as a function of time in seconds by T = 100 + 2t^2. (a) Determine the magnitude of the linear impulse due to the forces acting on the helicopter from t = 0 to t = 3 s. (b) Use the principle of impulse and momentum to determine how fast the helicopter is moving at t = 3 s.

Step 1

We are given the mass of the helicopter (9300 kg) and the thrust of its engine as a function of time (T = 100 + 2t^2, where T is in kN and t is in seconds). We need to find the linear impulse from t = 0 to t = 3 seconds and then use that to determine the velocity Show more…
