Question

Calculate the initial upward acceleration of a rocket of mass 1.3 x 10000 kg if the initial upward force produce by its engine is 2.6x 100000n

Answer 1

Answer:

Initial upward acceleration is 10.2m/s²

Explanation:

Mass of rocket=1.3*10⁻⁴ kg

Thrust Force F=2.6x10⁵ N

The net force acting on the rocket is ma.By Newton's second law of motion

          ma=F-mg

a=$\frac{F-mg}{m}$

a=$\frac{2.6*10^5 N-(1.3*10^(-4)kg)(9.8m/s^{2}) }{1.3*10^(-4)kg}$

a=10.2m/s²

Initial upward acceleration is 10.2m/s²
