Question

A rocket with a lift-off mass 3.5 × 104 kg is blasted upwards with an initial acceleration of 10 m/s2 . Then the initial thrust of the blast is (A)  3.5× 105 N  (B)  7.0 × 105 N  (C)  14.0 × 105 N  (D)  1.75 × 105 N

Here, thrust force is responsible to accelerate the rocket, so initial thrust of the blast. =ma =3.5× 104× 10 =3.5× 105N

Q. 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

$3.5 \times 10^{5} N$

$7.0 \times 10^{5} N$

$14.0 \times 10^{5} N$

$1.75 \times 10^{5} N$

Here, thrust force is responsible to accelerate the rocket, so initial thrust of the blast. $= ma$ $= 3.5 \times 10^{4} \times 10$ $= 3.5 \times 10^{5} N$

Q. 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

3.5×105N

7.0×105N

14.0×105N

1.75×105N
