Answer:
Final potential energy = 24 Joule
The velocity with which object must be thrown = m/s
Step-by-step explanation:
<u>Given:</u>
Mass of object, m = 0.30 Kg
Height of object, h = 8 m
Acceleration due to gravity, g = 10
a) Formula for Potential Energy:
Where m is the mass of object
g is acceleration due to gravity and
h is the height of object
Putting the values of m, g and h
b) Formula for initial and final velocity:
where v is the final velocity
u is the initial velocity with which the object is thrown
g is acceleration due to gravity and
h is the height obtained by object
here v = 0 at the height 8 m because it will come to rest at the point it attains the maximum height.
h = 8m
g = -10 (negative because the object's velocity is decreasing)
Putting the values to find 'u':
Answer:
15 cm
Step-by-step explanation:
If we have two sides of a parallelogram in the ratio 5:4, then the other two sides must also be in the same ratio.
If the perimeter is 54, we can create the following equation regarding the length of each side
As our value for x is 3, and we know that the value for the larger side is 5x, we can simply plug in x to get the length of the larger side
