Answer:
P.E = mgh
K.E = 1/2mv²
Explanation:
P.E = mgh
That is m= mass in kilograms, g=acceleration due to gravity and h= height in meters.
K.E = 1/2mv²
That is 1/2 of an object's mass multiplied by the velocity squared.
These values when compared seem to be the same. They are equal. If we convert them to the same units, they results to the value which is:
51.5 Hectograms = 5100 Grams
51,500 Decigrams = 5100 Grams
Hope this answers the question. Have a nice day.
The mass of the object doesn't matter. The change in its momentum is equal to the impulse that changed it ... 15 N-sec.
The most common one is junk food and sugary snacks are very very addicting! they are almost like drugs!!!
To find the momentum of an object, you use the equation P=M*V.(p=momentum, m=mass, v=velocity/speed/acceleration.) So, the equation here is P=5kg*2m/s or p=5*2. 5*2=10 P=10: So the momentum of the bowling ball is 10p.
