QI. A rocket climbing upward with a velocity of v, = 278.61 km/hr with an angle of 48°. The rocket release a sack when it flies at altitude H = 2888 m. (a) Determine the distance along the ground, R, measured from a point directly beneath the point of release, to where the sack hits the earth. (b) When the sack hit the ground, find the angle, d. (c) If the rocket start from rest at x = 0, and travels along the trajectory described by y? = [-120(10)°x] m, and the x component of acceleration is given as a, = (t²) m/s?, calculate the magnitude of rocket's velocity and acceleration when t = 12s. e = 48° y? = [-120(10) x] H R Figure QI QI.
