Question

A rocket with a lift-off mass

3.5 \times 10^{4} k g

is blasted upwards with an initial acceleration of

10 m / s^{2}

. Then the initial thrust of the blast is

Options:

A . 1.75×105 N

B . 3.5×105 N

C . 7.0×105 N

D . 14.0×105 N

Answer: Option C
:
C
Initial thrust on the rocket

F = m (g + a) = 3.5 \times 10^{4} (10 + 10) = 7.0 \times 10^{5} N
