Question

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

Answer 1

Answer:

199267.50

Explanation:

v= 30×5/18= 16.3

w=change in kinetic energy

w=1/2 m×v× v

w=1/2 × 1500× 16.3×16.3

w=199267.50

Answer 2

Answer:

difference between velocity

$60 - 30$

$30$

gravity =10m/sec

Explanation:

$1500 \times 30 \times 10$

450000
