Answer:

  • 625 Joules is the required Kinetic Energy.

Explanation:

Given:-

  • Mass of object ,m = 50kg
  • Velocity ,v = 5m/s

To Find:-

  • Kinetic Energy ,KE

Solution:-

As we have to calculate the Kinetic Energy of the object.

Kinetic Energy is defined as the energy possess by body due to its motion .

Kinetic energy can be calculated by using this Formula

KE = 1/2 mv²

where,

  • KE is the Kinetic Energy
  • m is the mass
  • v is the speed/velocity

Substitute the value we get

→ KE = 1/2×50×5²

→ KE = 1/2 × 50 × 25

→ KE = 25 × 25

→ KE = 625 J

  • Hence, the kinetic energy of the object is 625 Joules.

Answer:

Given :-

  • Mass = 50 kg
  • Velocity = 5 m/s

To Find :-

Kinetic energy

Solution :-

As we know that

 \huge \boxed{ \frak{KE \:  =  \frac{1}{2}  \times m {v}^{2}}}

KE is the Kinetic energy

M is the Mass

V is the Velocity

 \sf \mapsto \: KE =  \dfrac{1}{2}  \times 50 \times 5 {}^{2}

 \sf \mapsto \: KE =  \dfrac{1}{2}  \times 50 \times 25

 \sf \mapsto \: KE \:  = 25 \times 25

 \frak \red{KE \:  = 625 \: J }

Hence :-

The Kinetic energy of object is 625 Joules (J)
