Answer:
t = 160 minutes
Explanation:
Given that,
Distance of Uranus from Sun is
We need to find the time taken by the light to go from sun to Uranus if the velocity of light is constant in free space and it is equal to c.
So,
Since, 1 minute = 60 seconds
t = 160 minutes
So, 160 minutes is taken by the light.
The smaller the displacement, the smallest restoring force it will create.
As seen from the figure given below, The spring system follows the equation,
F = -Kx
where, x is the displacement
F is the restoring force
k is the spring constant
If , K is kept constant, then,
F is directly proportional to the displacement but it acts in opposite direction due to negative sign.

Hi there!
Since the ball is directed 60° above the horizontal, we must use its HORIZONTAL component to find its displacement.
We can take the cosine to do so:
vcosθ = 28.3cos(60) = 14.15 m/s
Since the ball is in the air for 5 sec, we can use the following equation:
displacement = velocity · time (d = vt)
Plug in the values:
d = 14.15 · 5 = 70.75 m
