Answer:
Answer:
We know that
K.E = Kinetic energy attain by object
m = Mass of the object
v = Velocity of the object
Given parameters:
K.E. of the object = 25 J
Velocity of the object ( v) = 5 m/s
⇒
K

50 = 25 × m
m = 2 kg
1st case:
When velocity is doubled, then
v = 10 m/s
m = 2 kg

2nd case:
When velocity is increased three times, then
v = 15 m/s

Step-by-step explanation:
Clarified butter is milk fat rendered from butter to separate the milk solids and water from the butterfat. Typically, it is produced by melting butter and allowing the components to separate by density.
