Question

The Tesla Roadster electric car is rated at 16.8kW how much energy does it use during a one hour car drive

Answer 1

Answer: $6.05\cdot 10^7 J$

Explanation:

Energy is related to power by:

$E=Pt$

where P is the power and t is the time. In this problem, we have:

$P=16.8 kW=16800 W$

$t=1 h=3600 s$

So, the energy used in one hour is

$E=(16800 W)(3600 s)=6.05\cdot 10^7 J$
