Guys plzzz plzzz ans this que 14. The rate of mass of the gas emitted from rear of
a rocket is initially 20 kg/s. If the speed of the gas
relative to the rocket is 800 m/s and mass of
rocket is 1000 kg, then the initial acceleration of
the rocket is :
(1) 4 m/s2
(2) 16 m/s2
(3) 6 m/s2
(4) 12 m/s2

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
