A toy rocket expels gas at the rate of 3kg/s. What is the initial force exerted on the rocket if it moves with the speed of 300 m/s?

the initial force exerted on the rocket is 900 N

Explanation:

The computation of the initial force exterted on the rocket is shown below:

Force exerter = Rate of change of momentum

= 300 m/s × 3kg/s

= 900 N

hence, the initial force exerted on the rocket is 900 N

we simply multiplied the rate with its speed so that the force could come

gravity

explanation:

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
