A rocket with a lift-off mass 3.5 x 10⁴ kg is blasted upwards with an initial acceleration of 10 m/s². The initial thrust of the blast is
Options
(a) 1.75 x 10⁵ N
(b) 3.5 x 10⁵ N
(c) 7 x 10⁵ N
(d) 14 x 10⁵ N
Correct Answer:
7 x 10⁵ N
Explanation:
Net upthrust = Weight + Blasted force
U = mg + 3.5 × 10⁴ × 10ms⁻²
U = 3⋅5 × 10⁴× 10ms⁻¹ + 3⋅5 × 10⁴ × 10ms⁻²
U = 7⋅0 × 10⁵N.
