Answer:

Given

Mass = 20 kg

Kinetic Energy = 1000 J

To Find

Velocity

Solution

We know that

\sf \longrightarrow KE=\dfrac{1}{2}mv^{2}⟶KE=

2

1

mv

2

Here

KE = Kinetic Energy

m = Mass

v = Velocity

Units

KE = Joule (J)

m = kilogram (kg)

v = metre/second (m/s)

According to the question

We are asked to find velocity

Therefore

\sf \longrightarrow v=\sqrt{\dfrac{2KE}{m}}⟶v=

m

2KE

Given that

Mass = 20 kg

Kinetic Energy = 1000 J

Hence

m = 20 kg

KE = 1000 J

Substituting the values

We get

\sf \longrightarrow v=\sqrt{\dfrac{2 \times 1000}{20}} \ m/s⟶v=

20

2×1000

m/s

\sf \longrightarrow v=\sqrt{\dfrac{2000}{20}} \ m/s⟶v=

20

2000

m/s

\sf \longrightarrow v=\sqrt{\dfrac{200}{2}} \ m/s⟶v=

2

200

m/s

\sf \longrightarrow v=\sqrt{100} \ m/s⟶v=

100

m/s

Therefore

\sf \longrightarrow v=10 \ m/s⟶v=10 m/s
