P= w/t and W= Work 
In this case, W= 6,700j, and T= 45 seconds
Power is the ratio of work  per unit time. When you perform a work in a given span of time, the ratio of work performed with respect to time is Called Power. 
si unit for Power is Watt (W) 
so, P= 6,700/45
P= 148 
Final answer is P=148

The mass of the car?
Nonamiya [84]

Answer:

1050 kg

Explanation:

The formula for kinetic energy is:

KE (kinetic energy) = 1/2 × m × v² where <em>m</em> is the <em>mass in kg </em>and <em>v</em> is the velocity or <em>speed</em> of the object <em>in m/s</em>.

We can now substitute the values we know into this equation.

KE = 472 500 J and v = 30 m/s:

472 500 = 1/2 × m × 30²

Next, we can rearrange the equation to make m the subject and solve for m:

m = 472 500 ÷ (1/2 × 30²)

m = 472 500 ÷ 450

m = 1050 kg

Hope this helps!
