Your friend claims he can throw a baseball straight up with a
speed of 80 mi/h. You do not
believe him, so you design an experiment that will enable you to
calculate the speed of a thrown
ball. You attach a 0.5-kg block to a vertical spring. The block
hangs a distance of 0.05 m below
the relaxed position. Your friend stands directly beneath the
hanging block and throws the
baseball straight up. He releases the ball at a distance of 2.4 m
below the hanging block. You
design the experiment so that the ball sticks to the block after
the collision. You observe that the
block-baseball combination rises a distance of 0.18 m after the
collision.
Do you believe that your friend can throw a baseball with a speed
of 80 mi/h?

a
baseball player bats a ball straight up with an initial speed of
109 miles. it reaches a height of s = 0.03t-0.003t ^ 2 miles after
t seconds. What is the speed of the ball when it is .0830 miles
from the ground?

1. When you throw a pebble straight up with initial speed
V, it reaches a maximum height H with no air
resistance. At what speed should you throw it up vertically so it
will go twice as high?
a. Insufficient information
b. 18 V
c. V sqrt(2)
d. 4 V
e. 8 V

A plane flying horizontally at an altitude of 5 mi and a speed
of 470 mi/h passes directly over a radar station. Find the rate at
which the distance from the plane to the station is increasing when
it is 7 mi away from the station. For full credit I expect to see a
well-labeled picture. Show all work. Round your final answer to the
nearest whole number. Do not round intermediate values. Include
units of measure in your answer.

A plane flying horizontally at an altitude of 2 mi and a speed
of 510 mi/h passes directly over a radar station. Find the rate at
which the distance from the plane to the station is increasing when
it is 3mi away from the station. (Round your answer to the nearest
whole number.)

The question:
A teacher is trying to figure out how fast he can throw a
Baseball, but doesn't have a radar gun. He does have the
following:
- Baseball
- Soft styrofoam Block ( In which the ball could become embedded
into during a collision)
- A level tabletop
- A metre stick
- A balance scale.
The teacher also has determined the coefficient of friction
between the block and table.
NOTE: The kinetic coefficient of friction is determined
while...

Assume that your friend claims that he can run 20 km in less
than an hour and a professional sports team will recruit him after
graduation based on this outcome so he does not worry about his GPA
at the university. You would like to test this claim and take a
random sample of 34 runs this year and find that he averaged 58.2
minutes. Assume that the standard deviation of his runs is 8.5
minutes and it is normally...

- Your friend claims he has a fair coin; that is, the
probability of flipping heads or tails is equal to 0.5. You believe
the coin is weighted. Suppose a coin toss turns up 15 heads out of
20 trials. At α = 0.05, can we conclude that the coin is fair
(i.e., the probability of flipping heads is 0.5)? You may use the
traditional method or P-value method.

There is a myth in baseball that a pitcher can throw a “rising
fastball” meaning that if the ball is thrown horizontal, the Magnus
Force created from backspin will overcome gravity and the ball will
literally rise in the air. This assignment is to be done
individually. 95 speed of the baseball in mph. a. Calculate the rpm
that is needed to generate enough Magnus Force to overcome the
force of gravity. Note: Be careful with units and show all...
