A rocket of mass 5.8 × 105 kg is in flight. Its thrust is directed at an angle of 55.0o above the horizontal and has a magnitude of 7.88 × 106 N. Find the direction of the rocket’s acceleration. Give the direction as an angle above the horizontal. (g = 9.80 m/s2)

When it is 145 $\mathrm{m}$ above the ground, a rocket traveling vertìcally upward at a constant 8.50 $\mathrm{m} / \mathrm{s}$ relative to the ground launches a secondary rocket at a speed of 12.0 $\mathrm{m} / \mathrm{s}$ at an angle of $53.0^{\circ}$ above the horizontal, both quantities being measured by an astronaut sitting in the rocket. Air resistance is too small to worry about. (a) Just as the secondary rocket is lunched, what are the horizontal and vertical components of its velocity relative to (i) the astronaut sitting in the rocket and (ii) Mission Control on the ground? (b) Find the initial speed and launch angle of the secondary rocket as measured by Mission Control. (c) What maximum height above the ground does the secondary rocket reach?
A rocket is fired upward from the Earth's surface such that it creates an acceleration of $19.6 \mathrm{~m} / \mathrm{s}^{2}$. If after $5 \mathrm{~s}$, its engine is switched off, the maximum height of the rocket from Earth's surface would be: (a) $980 \mathrm{~m}$ (b) $735 \mathrm{~m}$ (c) $490 \mathrm{~m}$ (d) $245 \mathrm{~m}$
