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
