the question is simply asking you to find the circumference of the circle. the formula for the circumference of a circle is c = Pi x d (d - diameter...in your case you have the radius and therefore the formula you want to use is c = Pi x 2r (r = radius).
Suppose a runner covers a distance of 5322 feet in a 6 minutes and 11,531 feet in 13 minutes. So how much distance does the runner cover in 16 minutes?
2.1
Divide the distance by the time. That will give you the speed in kilometers/hour. Then divide that by 3.6 to convert to meters/second.
Just divide distance/time. 240 divided by 4 is 60. So your answer is 60 km/h
In 1 hour it travels 60 km Hence In 6 hours it travels 6 x 60 = 360 km
If he covers 1/2 the length of the circular path, then the beginning and end of histrip are at opposite ends of a diameter of the circle.Diameter = 2 x radius = 2 x 5 = 10 meters.
"Distance" is how far you walked or drove from the time you start out untilthe time you stop, regardless of where the places are."Displacement" is the length of the straight line between the place you start fromand the place where you stop, regardless of the path you follow to get there.If you end up where you started, then the displacement is zero.
Velocity is displacement divided by time
Just as distance and displacement have distinctly different meanings), so do speed and velocity. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance.
When a body covers a displacement in the opposite direction of our reference direction then displacement will be negative.
If a body travels at a constant speed it will travel a certain distance (doesn't matter how far for our purposes). If it's accelerating then its speed is constantly increasing and therefore it covers more distance over every increment of time that it would if it were moving at its initial speed. So, acceleration increases displacement.
If the fountain is square, then the base covers 400 square feet of ground. If the fountain is circular, then the base covers 314.2 square feet of ground. (rounded)
Athlete covers 2pi radians in 40 s. So angular velocity = pi / 20 rad/s Hence the velocity = r w r = 100 m. So v = 5 pi m/s Hence the distance covered in 2 min 20 s ie 140 s = 700 pi metre. Displacement is the shortest distance between initial and final position In 140 s, 3 full rotation and one half rotation. So the he will be diametrically opposite. Hence the displacement is equal to 200 m ie diameter of the circular track.
Mark lee runs three laps of a 200-m lap racetrack. Calculate the total distance and the displacement if he ended up in middle from where he started running.
The equation which covers this is s = ut + at2/2 where s is distance (ie displacement), u is initial velocity, t is time and a is the acceleration. This is a parabola with an initial (t=0) slope equal to u. The above equation comes from simple integration of the velocity versus time equation v=u+at, using an origin for distance s=0 at t=0.
The object's mass and weight determines the force and distance, the greater the force, the less distance it covers. However, when a knife cuts the object, it covers less force and more distance.
A car covers a distance of 242 km in 2.2 hours how much distance will it cover in 1 hour
