Two ball are fired from ground level, a distance
d apart. The right one is fired vertically with
speed v. At the same time the left ball is fired
with speed u and at angle with respect to
the ground. What should u and
be in order
the left ball collides with the right one when the latter reaches
its highest point?
Given d, what should v be so that the speed u is minimum?
Homework Answers
Direction of firing the projectile should be tan-1 (uy/ux)
= tan-1 (V2/gd)

a cannon ball was fired from a cannon on level ground. an observer in a balloon observed the top of the ball’s flight. as the ball barely misses the observer, he measures a speed of 111 m/s and a height of 75.2 m. how far (horizontally) from the balloon does the ball land? from where was it fired? at what angle was the cannon fired?

A ball is thrown straight up at speed in the presence of gravity. (a) Ignoring air resistance at first, what is the maximum height the ball reaches? (b) Now include Newtonian (quadratic) air resistance, with drag coefficient c. Letting the direction point upwards, write down the equation of motion (be careful with the signs). (c) Solve the equation of motion to find v(t)(= (t)). Remember to check that v(0) = . (d) Without integrating anything yet, calculate the time at...

You and your friend are standing on level ground 25.0 m apart. They are getting ready to test their tennis ball cannon, which is positioned next to your friend. The cannon is aimed upward at an angle of 50° with respect to the ground and has an adjustable launch speed. a) The cannon fires. Draw a motion diagram for the tennis ball while it is in flight (include several “v” arrows and one “delta v” arrow). b) What launch speed...

A small, spring-loaded cannon launches a golf ball from level ground with an initial speed vi at an angle θi with the horizontal. The golf ball lands a horizontal distance R from its launch point. The highest point the golf ball reaches during its flight is a distance R/12 above the ground. In terms of R and g, find the following. (You may ignore air resistance.) (a) the time interval during which the golf ball is in motion t =...

A ball of mass M is attached to one end of a spring of
stiffness k and relaxed length
L0. The other end of the spring
is attached to the ceiling. When the ball hangs at rest in
equilibrium at the end of the spring it is located at the origin of
the coordinate system shown and the spring’s length is
Leq.

A charge configuration with two
charges of opposite sign but the same magnitude, q, and a
separation distance, d, is called an electric dipole. The
electric dipole moment, or EDM, is a vector, p,
with a magnitude p = qd and a direction from the
negative charge towards the positive charge. When such a dipole is
placed in a region of electric field, it will experience a torque
which depends upon the angle, θ, between the directions of the EDM,...
