Question

20. A rocket outha lift af mass 20,000 km
.
blasted upwards with an initial acceleration 5.0m/s^2. Calculate the initial
thrust (force ) of the blast.​

Answer 1

Answer:

Given m = 20000 kg

a=5ms −2

(against gravity) since the rocket has to move upwards against gravity the total initial thrust of the blast is given by

F=ma+mg

=m(a+g)=20000(5+9.8)

=296×10 5N
