How much energy is required to a accelerate a 2kg block from rest to a final speed of 5m/s?

Kinetic energy is a form of energy that an entity or particle possesses due to its motion.
The relation between the object's mass and its speed.
KE = \frac{1}{2} mv^2
Step 1: Calculating the kinetic energy required to accelerate the block
Given that
Mass of the block = 2 kg
Final speed v_f = 5 m/s
At the rest, Initial kinetic energy is zero KE_i = 0
At the end, Final kinetic energy KE_f = \frac{1}{2} mv_f^2
KE_f = \frac{1}{2}(2kg)(5m/s)^2
KE_f = 25 kg m^s/s^2
Final kinetic energy KE_f = 25 joules
The amount of energy needed to accelerate a block = Change in kinetic energy
Change in kinetic energy \Delta KE =KE_f - KE_i
\Delta KE = 25 \text{ joules } - 0 \text{ joules }
\Delta KE = 25 \text{ joules }
Therefore, the amount of energy required to accelerate the block, \Delta KE = 25 \text{ joules }
