Question

A car is moving with a uniform velocity of 15 m/s. What is the K.E. of a boy of mass
40 kg sitting in the car?
​

Answer 1

Step-by-step explanation:

use formula 1/2mv sq then put the values

Answer 2

Answer:

the answer is 4500 J

Step-by-step explanation:

the formula for KE is 1\2mv^2

so

M=40kg

velocity=15m/s

putting it in equation

1/2×40(15)^2 = 20×225= 4500 J

J stands for joule
