Answer:
225 joules
Explanation:
Question says that,
A ball of mass 2kg is thrown upwards with a speed of 15m/s.
Find the kinetic energy.
We know that,
→ K.E. = ½mv²
Where,
- ‘m’ denotes the mass of the ball.
- v is the velocity
Hence,
→ K.E. = ½*2*(15)²
→ K.E. = 1*225
→ K.E. = 225 J
∴ Kinetic energy of the ball is 225 joules.

Answer:
Given :-
- A ball of mass 2 kg is thrown up with a speed of 15 m/s.
To Find :-
- What is the kinetic energy of the ball at the time of throwing.
Formula Used :-
Kinetic Energy Formula :
where,
- K.E. = Kinetic Energy (J)
- m = Mass (kg)
- v = Velocity (m/s)
Solution :-
Given :
- Mass = 2 kg
- Velocity = 15 m/s
According to the question by using the formula we get,
By putting those values we get,
