Answer 1

Answer:

kinetic energy = 1/2 m v^2

=1/2 x 8.90 x 2.56 x 2.56

=29.16352

Answer 2

$\Large{\underline{\underline{\bf{Solution :}}}}$

★ Given :

Velocity of object (v) = 2.56 m/s

Mass of object (m) = 8.90 kg

__________________________

★ To Find :

We have to find the kinetic energy (K.E) of the object.

__________________________

★ Solution :

We know the formula to calculate the kinetic energy of a object.

$\Large{\implies{\boxed{\boxed{\sf{K.E = \frac{1}{2} m v^2}}}}}$

____________[Put Values]

$\sf{→K.E = \frac{1}{2} \times 8.90 \times (2.56)^2} \\ \\ \sf{→ K.E = \frac{\cancel{8.90}}{\cancel{2}} \times 6.55} \\ \\ \sf{→ K.E = 4.45 \times 6.55} \\ \\ \sf{→K.E = 29.147} \\ \\ \sf{→K.E ≈ 29.15 \: J} \\ \\ \Large{\implies{\boxed{\boxed{\sf{29.15 \: J}}}}}$
