Question

A rocket with a lift-off mass 3.5×10⁴kg is blasted upwards with an initial acceleration of 10m/s². Then ,the initial thrust of the blast is [AIEEE 2003] ​

Answer 1

Given:

mass of the rocket = 3.5 × 10^4 kg

initial acceleration = 10 m/s^2

We know that, thrust is a push or a pull with tends to change the position of the body.

In simple language thrust = Force

Force = mass × acceleration or Thrust = mass × acceleration

(putting given values)

F = 3.5 × 10^4 × 10

F = 3.5 × 10^5 Newton

Hence, we got the required force as 3.5 × 10^5 N

So, the initial thrust = 3.5 × 10^5 N

Hope this helped you dear...

Answer 2

Explanation:- Here, thrust force is responsible to acceleration the rocket,so initial thrust of the blast

• ma = 3.5×10⁴×10

3.5 × 10⁵N Answer
