Large accelerations are often measured in g where 1g=10m/s 2 .Part A3g for five minutesHow much speed can you gain at 3g in five minutes?

Sure, let's break this down:

1. First, we need to convert the time from minutes to seconds because the acceleration is given in m/s^2. So, 5 minutes = 5 * 60 = 300 seconds.

2. Next, we need to calculate the acceleration in m/s^2. Given that 1g = 10m/s^2, then 3g = 3 * 10 = 30m/s^2.

3. Finally, we use the formula for acceleration which is final velocity = initial velocity + (acceleration * time). Assuming the initial velocity is 0 (starting from rest), the final velocity would be 0 + (30m/s^2 * 300s) = 9000m/s.

So, you can gain a speed of 9000m/s at 3g in five minutes.
