2. A racecar has a mass of 1500 kg. What is its KE in joules if it has a speed of 110 km/hr?

sertanlavr [38]

Answer:

7.0 × 10^5 J

Step-by-step explanation:

First we convert the speed of 110 km/hr to metre-per-seconds

v = 110×(1000/3600)

v = 30.56 m/s

m = 1500 kg

$kinetic \: energy \: = \frac{1}{2} m {v}^{2}$

= 0.5 × 1500 × (30.56)²

= 700231.5

= 7.0 × 10^5 J
