Question

The formulae for kinetic energy is E =-mv2.

Find the value of E when m= 900 and v=1.3,

Answer 1

Answer: ΔKE = 760.5 Joules

Explanation:

Isnt the formula for ΔKE = 0.5m*v^2???

Im not going to use that formula you gave me, its wrong.

900/2 = 450

1.3^2 = 1.69

450 x 1.69 = 760.5 Jules

This is also the wrong subject btw
