Using the given data predict, average velocity & average speed of the athlete.

Answer #1

If a car moving along a circular track of radius 300 m completes
540° in 5 minutes with constant angular velocity, what are its arc
length traversed, angular velocity, and tangential velocity?

Jogger A cuts directly north across the diameter of the circular
track, while jogger B takes the full semicircle to meet his partner
on the opposite side of the track. Assume their common average
speed is 3.0 m/s and the track has a diameter of 200 meters .
A) How many seconds ahead of jogger B does jogger A arrive?
B) How do their travel distances compare? in meters
C) How do their displacements compare? in meters north
D) How...

A runner runs around a circular track. He completes one lap at a
time of t = 471 s at a constant speed of v = 3.1
m/s.
What is the radius, r in meters, of the track?
What was the runners centripetal acceleration,
ac in m/s2, during the run?

A runner in a circular track was observed running at an angular
velocity of 0.230 rad/s. 2.4 seconds later, she was observed
running at 0.050 rad/s. The radius of the circular track is 61m
Show work!!!
a) What is in radians/second2 her angular
acceleration during the 2.5 seconds?
b) What is her speed in meters per second at the end of the 2.5
seconds?
c) What is in meters/second2
her tangential acceleration during the 2.5 seconds?
d) What is in meters/second2
her centripetal acceleration...

A 1.4 kg vehicle travels at a constant speed of 6.2 m/s around a
circular track that has a radius of 6.3 m.
a.) What is the magnitude of the acceleration of the
vehicle?
b.) What is the average velocity of the vehicle during one
complete revolution?

A person starts to run around a square track with sides of 50 m
starting in the bottom right corner and running counter-clockwise.
Running at an average speed of 5 m/s, the jogger runs for 53.80
seconds. What is the difference between the magnitude of the
person's average velocity and average speed in m/s? (please provide
detailed explanation)

The roller coaster in Figure P6.36 starts with a velocity of
15.8 m/s. One of the riders is a small girl of mass 40 kg. At
points B and C, the track is circular with the radii of curvature
given in the figure. The heights at points A, B, and C are hA= 24
m, hB = 34.15 m, and hC=0 m. You may assume the track is
frictionless. At point B r = 10m, at point C r =...

Two seconds after being projected from ground level, a
projectile is displaced 40 m horizontally and 53 m vertically above
its launch point. Its horizontal component of initial velocity is
v0x=20 m/s. Its vertical component of initial velocity
is v0y=36 m/s. At the instant the projectile reaches
maximum height above ground level, the displacement is x=74 m.
