Question

What is the work to be done to increase the velocity of a car from 30km/h to 60km/h if the mass of the car is 1500kg??​

Answer 1

ANSWER :

Work done to increase the velocity of a car from 30 km/hr to 60 km/hr is 2025 KJ

EXPLANATION :

Work = Force × displacement

F = ma = 1500 a

v² - u² = 2as

s = (v² - u²) / 2a

s = (60 + 30)(60-30)/2a

s = 90 × 30 /2a

s = 2700/2a

Work = 1500a × 2700/2a

Work = 1500 × 2700/2 = 2025000 J

Work = 2025 KJ
