Determine Jupiter's velocity
First, we calculate the circumference (C) of Jupiter:
Substitute values for r and
Next, convert time to seconds:
The velocity is then calculated as:
m/s
<em>Hence, Jupiter's velocity is 1306.76m/s</em>
Answer:
Explanation: It is inertia that causes the passengers to move toward the right side of the car. As the car swerves to left, passengers' body continues their motion as hitherto and as such it causes the passengers to move toward the right side of the car.
Answer:
B. a conversion factor
Explanation:
The expression "1 in. = 2.54 cm" is called a conversion factor.
With this expression inches can be converted to centimeters.
Inversely the expression can also be used to convert centimeters to inches
By rearranging the equation we get
The statement which shows the equal nature of two different expressions is called an equation
Rule of thumb is a general approximation of a result of a test or experiment.
Answer:
Explanation: Two possible solutions
in the absence of friction
mgh = ½mv²
h = v²/2g = 24.4²(2(9.81) = 30.344... = 30.3 m
if enough rolling friction exists to keep the ball from sliding, but ignoring air resistance and assuming the ball is already rolling smoothly at the start
mgh = ½mv² + ½Iω²
mgh = ½mv² + ½((2/3)mR²)(v/R)²
2gh = v² + (2/3)v²
2gh = (5/3)v²
h = (5/6)v²/g
h = (5/6)24.4²/9.81 = 50.5742 = 50.6 m
