Answer:
kinetic energy will be equal to 0
Explanation:
this is because at final position velocity of body will become zero.
kinetic energy eill be 8 times
Answer:
The answer to your question is: Chemical change
Explanation:
Chemical Change is a change where substances change their properties because new substances are obtain. This is the right answer.
Compressibility
is a property in which a substance is compressed but it continous being the being so this answer is wrong.
Malleability is a property in whcih substances are flattened into thin sheets but they don't change their properties. This answer is wrong.
Physical Change is a change in which a substance changes its physical state but the properties are the same than the original substance, this answer is wrong.
Answer: 1608.39 J
Explanation: Given that the
mass M = 42kg
U = 11.5m/s
V = 3.33m/s
how much work did friction do
Work done = Force × distance
Work done = Ma × distance
But acceleration a = V/t
Work done = M × V/t × d
Work done = M × V × d/t
Where d/t = velocity
Therefore,
Work done = M × U × V
Work done = 42 × 11.5 × 3.33
Work done = 1608.39 J
