Firstly we calculate the mass of the body . As we know that Kinetic Energy is the energy possess by body due to its motion.
Where
KE is the Kinetic Energy
m is the mass of the body
v is the final velocity
Substitute the value we get
→ 25 = 1/2×m× 5²
→ 25×2 = m × 25
→ 50 = m × 25
→ m = 50/25
→ m = 2 kg
Mass of the object is 2kg .
If the velocity of the object increase by three times .Then the new velocity is 3 × 5 = 15m/s
Now calculating the New kinetic Energy
→ KE' = 1/2× 2 × 15²
→ KE' = 15×15
→ KE' = 225 J
Therefore, the new kinetic energy of the object is 225 Joules.

Firstly we calculate the mass of the body . As we know that Kinetic Energy is the energy possess by body due to its motion.
• KE = 1/2mv²
Where
KE is the Kinetic Energy
m is the mass of the body
v is the final velocity
Substitute the value we get
→ 25 = 1/2×m× 5²
→ 25×2 = m × 25
→ 50 = m × 25
→ m = 50/25
→ m = 2 kg
Mass of the object is 2kg .
If the velocity of the object increase by three times .Then the new velocity is 3 × 5 = 15m/s
Now calculating the New kinetic Energy
• KE ' = 1/2mv²
Substitute the value we get
→ KE' = 1/2× 2 × 15²
→ KE' = 15×15
→ KE' = 225 J
Therefore, the new kinetic energy of the object is 225 Joules.
