How much force does an 60 kg astronaut exert on his chair while accelerating straight up at 8m/s squared?

force=mg+ma

To find the force exerted by the astronaut on his chair, we need to use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration. In this case, the mass of the astronaut is given as 60 kg and the acceleration is given as 8 m/s^2.

So, we can use the formula:

Force = mass × acceleration

Plugging in the given values:

Force = 60 kg × 8 m/s^2

Calculating this:

Force = 480 N

Therefore, the force exerted by the 60 kg astronaut on his chair while accelerating straight up at 8 m/s^2 is 480 Newtons.
