How much power is needed to accelerate an object with a mass of #6# # kg# and a velocity of #3# # ms^-1# at a rate of #1# # ms^-2#?

Answer 1

The power is #=18W#

The mass is #m=6kg#
THe acceleration is #a=1ms^-2#

According to Newton's Second Law

#F=ma=6*1=6N#
The velocity is #=3ms^-1#

The power is

#P=Fv=6*3=18W#

Answer 2

To calculate the power needed to accelerate the object, you can use the formula:

Power = Force * Velocity

Since Force equals mass multiplied by acceleration:

Force = mass * acceleration

Substituting the given values:

Force = 6 kg * 1 m/s^2 = 6 N

Now, power equals force multiplied by velocity:

Power = 6 N * 3 m/s = 18 W

Therefore, the power needed to accelerate the object is 18 watts.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
