Question

What is the kinetic energy of a toy truck with a mass of 0.75 kg and a velocity of 4 m/s? (Formula: ) 3 J

Answer 1

here the given the value is mass (m)=0.75kg, velocity (v)=4 m/s

formula is

1/2×mv^2

1/2×0.75×4^2

6 J

Answer is 6 Joule

Answer 2

m= 0.75kg

v= 4m/s

now K(kinetic energy) =

$\frac{1}{2} m{v}^{2}$

=1/2 x 75/100 x 4 x 4

=1/2 x 3/4 x 4 x 4

= 3x 2

= 6J

i think it is 6J bruh
