Question: A Rocket fires two engines simultaneously. One produces a thrust of 725N directly forward, while the other gives a 513N thrust at 32.4o above the forward direction. Find the magnitude and direction (relative to forward direction) of the resultant force that these engines exert on the rocket.
Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars (highly compact stars consisting only of neutrons).
