A particle is moving along a straight line with an initial
speed of si = 6.0 m/s at time t = 0 s.
If the acceleration of the vehicle is a = -2.0 m/s2,
select all possible speed values of the particle
at time t = 4 s?

Full-time Ph.D. students receive an average salary of $12,837
according to the U.S. Department of Education. The dean of graduate
studies at a large state university feels that Ph.D. students in
his state earn more than this. He surveys 44 randomly selected
students and finds their average salary is $14,445, and the
population standard deviation is $1500. With α = 0.05, is the dean
correct?

A canon is firing a projectile. Select an angle for a launch.
Choose an angle between 15 and 75 degrees.
Initial speed is 22 m/s. Mass is 7.3g. Diameter of projectile is
0.25m.
Determine the vertical and horizontal components of the
projectile.
Calculate the range of the projectile. Write down the equation
used to solve for the range.

Projectile in 2D: A ball is thrown with initial speed V , at an
angle θ above the horizontal, over flat ground. Show that the
motion is restricted to a single plane. Neglecting air resistance,
find (a) the time taken for the ball to reach the ground; (b) the
maximum height reached by the ball; (c) the horizontal distance
travelled by the ball before hitting the ground (range); (d) the
kinetic and potential energies at the position of maximum height...

A projectile is launched from a cannon; it has an initial speed
of 85 m/s at an angle of 33 degrees above horizontal. The muzzle of
the cannon is 2.5 meters above the ground. How far down range will
