Question

A spacecraft has a mass of 50 000 kg and the accelerating force is 225 000 N. Calculate the acceleration of the spacecraft\/

Answer 1

Answer:

F=ma

a=225000/50000

=4.2m/sec2

hope so helpful

Newton's three laws of motion may be stated as follows:

✒1st law- Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.

✒2nd law- Force is directly proportional to the rate of change of momentum and applies in the same direction as it. Force equals mass times acceleration.

✒3rd law- For every action there is an equal and opposite reaction.
