Based on Newton's laws of motion, which combination of rocket bodies and engines will result in the acceleration of 40 m/s2 at the start of the launch?

The answer is "Body 1 + Engine 2 "

Explanation:

Please find the complete question in the attached file.

The Rocket Club plans to start a pair of model rockets.

Three potential motors are there. A table of four columns of three ranks.

The body has entries 1, 2, and 3 for the first column.

In the second column, the entries are 500, 1500, 750.

Engine entries 1, 2, 3 in the third column.

Forces (Newton) has entries 25, 20, 30 in the Fourth Column.

On the basis of Newton's movement rules, Body 1+Engine 2 would accelerate the start-up of a mixture of rocket bodies and motors by 40 m/s2. At launch.

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

the answer would be a
