If a car engine does 600,000 j of work over a 500m distance and the mass of the car is 250kg then what is the final velocity of the car?

Given that

Work = 600,000 J ,

distance(S) = 500 m ,

mass (m) = 250 Kg ,

Determine the velocity of car (v) = ?

                 We know that,

                                Work = Force × distance

                               => Force = Work ÷ distance

                                              = 600,000 ÷ 500

                                              = 500 N .

                   Also Force F =  m.a  ; from Newtons II law

                                      500 = 250 × a  

                                             a = 2 m/s.

Final Velocity from the given  formula

                                     V² = u² + 2.a.s

                                         = 0 + 2 × 2 × 500

                                         = \sqrt{2000}

                                      v = 44.7 m/s

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
