Problem 10.40
A soccer ball, which has a circumference of 70.0 cm, rolls 12.0 yards in 3.45 s .
Part A
What was the average angular speed of the ball during this time? (units= rad/s)
circumference, P = 70 cm
r = P/(2*pi)
r = radius of ball = 0.7/(2*pi) = 0.111 m
distance traveled = 12 yard = 10.97 m
time taken = 3.45 sec
v = speed = distance travelled/time
v = 10.97/3.45 = 3.18 m/sec
Now we know that
V = w*r
w = V/r = 3.18/0.111 = 28.65 rad/sec

A size-5 soccer ball of diameter 21.1 cm and mass 428 g rolls up a hill without slipping, reaching a maximum height of 4.1 m above the base of the hill. We can model this ball as a thin-walled hollow sphere. At what rate was it rotating (in rad/s ) at the base of the hill?
An automobile traveling at 70.0 km/h has tires of 50.0 cm diameter. (a) What is the angular speed of the tires about their axles? rad/s (b) If the car is brought to a stop uniformly in 40.0 complete turns of the tires (without skidding), what is the magnitude of the angular acceleration of the wheels? rad/s2 (c) How far does the car move during the braking? m
A bowler throws a bowling ball of radius R = 11 cm down
a lane. The ball slides on the lane with initial speed
vcom,0 = 11.0 m/s and initial angular speed
ω0 = 0. The coefficient of kinetic friction
between the ball and the lane is 0.22. The kinetic frictional force
fk acting on the ball causes a
linear acceleration of the ball while producing a torque that
causes an angular acceleration of the ball. When speed
vcom has...

The angular acceleration e. The acceleration...
Shrinking Loop. A circular loop of flexible iron wire has an initial circumference of 160 cm , but its circumference is decreasing at a constant rate of 12.0 cm/s due to a tangential pull on the wire. The loop is in a constant uniform magnetic field of magnitude 0.500 T , which is oriented perpendicular to the plane of the loop. Assume that you are facing the loop and that the magnetic field points into the loop. Part A Find...

A 88.0 kg soccer player jumps vertically upwards and heads the 0.45 kg ball as it is descending vertically with a speed of 23.0 m/s. If the player was moving upward with a speed of 4.20 m/s just before impact. (d) What will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic? (Note that the force of gravity may be ignored during the brief collision time.) (e) If...
