Answer:
31-40 m/s
Explanation:
The kinetic energy of an object is given by :
m is mass of the object
v is velocity
If mass of an object is constant, its kinetic energy depends only on velocity. It means if the velocity is more, it will have maximum kinetic energy. For the interval of 31-40 m/s, the kinetic energy of the object is maximum.
Answer:
Explanation:
Missing question:
What is the object's acceleration?
Solution:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time taken for the change in velocity
For the object in this problem,
u = +25 m/s
v = +15 m/s
t = 2.0 s
Substituting,
And the acceleration is negative because its direction is opposite to that of the velocity.
