Question

How much kinetic energy does a 0.30-kg stone have if it is thrown at 44 m/s?

O 440J
O 510 J
O 580J
0 290

Answer 1

290

Step-by-step explanation:

the reason is that the formula for kinetic energy is half m×v².

you divde half by 0.30 multiply by 44×44

you get 290.4

then you round it to significant figures to get 290

Answer 2

0 290
