Forms of Energy

Energy is described as the capability to accomplish a task, like the ability to push a block by applying force on it. It is a quantitative property that is used to accomplish work on an object.

Question

2/230 The third stage of a rocket is injected by its booster
with a velocity u of 15 000 km/h at A into an un-
powered coasting flight to B. At B its rocket motor
is ignited when the trajectory makes an angle of 20⁰
with the horizontal. Operation is effectively above
the atmosphere, and the gravitational acceleration
during this interval may be taken as 9 m/s², con-
stant in magnitude and direction. Determine the
time t to go from A to B. (This quantity is needed
in the design of the ignition control system.) Also
determine the corresponding increase h in altitude.
