Question

given that the kinetic energy of an object is 100 J if the mass of object is 2 kg then find its speed​

Answer 1

Solution:-

Given:-

• kinetic energy = 100 J
• Mass = 2 Kg

According to the question by using the formula we get,

⇛1/2 × 2 × v² = 100

⇛v² = 100

⇛v, = √100

⇛v = 100 m/s

➟The speed of an object is 10m/s.
