Answer:
Speed only defines the magnitude of how fast an object is moving from one point to another. This is a scalar quantity (Only Value)
Velocity defines both how fast an object is moving and also in what direction the object is moving. This is a vector quantity (Value + Direction)
You got it right on the top 3
Answer:
x = -6.5 meters
Explanation:
The position of a ball as a function of time t is given by :
..................(1)
Where t is time in seconds
We need to find the position of the ball at 1.9 s. It can be simply calculated putting t = 1.9 s in equation (1) as :
x = -6.5 meters
So, the position of the ball at 1.9 seconds is -6.5 meters. Hence, this is the required solution.
Explanation:
max potential your welcome i love helping outhers :)
You can solve this using Kepler's 3rd law. T is proportional to r^1.5. T(J) = T(E)*5.2^1.5 = 11.86 years.
<span>You can also solve it the hard way: Find M (sun's mass) and r(Jupiter's orbital radius) in m. Then use Kepler's equation T = 2pi*r^1.5/sqrt(GM).</span>
