Please state the options and I will answer to the best of my abilities XD
So what you wanna do is take your two givens. 22 and 3. Now you wanna take 22 and divide that by 3. And that gives you 7.33. Now if your answer HAS to be a whole number it'll be 66.
Answer:
a = 1 m/s^2
Explanation:
if we assume that right is the positive x direction and y is the negative x-direction then we get:
Fr = 8N
Fl = -3N
We then find the net force acting upon the object
Ft = Fr + Fl
Ft = 8N - 3N
Ft = 5N
After we find net force acting upon the object we can then use Newton's 2nd Law to find its acceleration.
Ft = m*a
Isolate accerleration
a = Ft / m
a = 5N / 5kg
a = 1 m/s^2
Explanation:
the question it's not complete as I don't know the height as the formula for potential energy is : <u>PE = </u><u>mgh</u>
<em>(m) - mass acceleration due to gravity </em>
<em>(g) - acceleration due to gravity </em><em> </em><em>(</em><em>9</em><em>.</em><em>8</em><em> </em><em>m</em><em>/</em><em>s2</em><em>)</em>
<em>(h) - height</em>
Answer:
It has potential energy
PE = 15450.75 J
Explanation:
we know its potential energy because the carriage is not moving, although it can
PE = mgh
in this case, m is 75, h is 21, and g is always 9.81
plug these in: PE = (75) (21) (9.81)
your answer: PE = 15450.75 J
