Question

Engineers at the Space Centre must determine the net force needed for a rockets engine to achieve an acceleration of 70 m/s2. Assume the rocket is in outer space with no gravitational or other forces acting on it. If the mass of the rocket is 45 000 kg, what force is required to be produced by the rocket engines?

Answer 1

3,150,000 Newtons

Step-by-step explanation:

F=M*A

F=45,000kg times (*) 70 m/s squared

F=3,150,000N (newtons)

Answer 2

3,150,000N

Step-by-step explanation:

According to Newton's second law;

F = mass * acceleration

Given

Mass = 45000kg

acceleration = 70m/s^2

Substitute

F = 45000 * 70

F = 3,150,000N

Hence the force required to be produced by the rocket engines is 3,150,000N
