The table below shows the energy of a 10 kg ball as a function of velocity. How much energy will the ball have at 10 m/s?velocity (m/s) 0, 2, 3, 6, 10Energy (joules) 0, 20, 45, 180, ??
Accepted Solution
A:
Answer:At [tex]v=10\ ms^{-1}[/tex] energy of the ball will be = [tex]500\ Joules[/tex]Step-by-step explanation:Given:Mass of ball =10 kgThe table for velocity vs Energy is given.Velocity[tex](ms^{-1})=0,2,3,6,10[/tex]Energy[tex](Joules)=0,20,45,180,E[/tex] Energy is in terms of velocity is given by:[tex]E=\frac{1}{2}mv^2[/tex]where [tex]m[/tex] represents mass and [tex]v[/tex] represents velocity.∴ at velocity = [tex]10\ ms^{-1} [/tex]Energy = [tex]E=\frac{1}{2}(10)(10)^2[/tex][tex]E=5\times100[/tex]∴ [tex]E =500\ Joules[/tex]∴ At [tex]v=10\ ms^{-1}[/tex] energy of the ball will be = [tex]500\ Joules[/tex]
