Bouncy
Question
Find the average force exerted by a bouncing ball on the floor as it repeatedly
bounces. Assume 100% restitution, i.e., the speed just after the bounce is equal to the
speed just before, and there is no kinetic energy lost during the bounc
Road Trip
Problem statement:
Using the Length of the car as the scale: L=188.4 inches = 4.785 m
Width of gap between end of bridge and the far side. w=10 m.
Add another meter for the landing margin and we can use W=11 m for the
horizontal distance covered
Satellite in orbit 2
Problem statement:
Scientists want to place a cfw_msat kg satellite in orbit around Mars. They plan to have
the satellite orbit at a speed of cfw_vsat m/s in a perfectly circular orbit. Here is some
information that may help solve thi
Rod
Question
Show that the parallel axis theorem applied to a rod whose axis of rotation is
perpendicular to is length gives the same answer as direct
integration.L/2LL/2mmxdxxdx
Solution
In the first case the axis of rotation is through the centre of mas
Eratosthenes measures the earth.
It was around 250 BCE when Eratosthenes was a librarian in the famous library of
Alexandria He discovered in his reading that there was a yearly festival in the town of
Syene (modern Aswan) on June 20. On that date, and on
A Cart Collides with a Soft Wall
Problem statement:
A cart collides with a soft wall. A force probe on the cart measures the force of the
wall on the cart as a function of time.
The cart + force probe has mass 0.485 kg. Determine the change in speed of th
2D Elastic Collision in the Centre-of-Mass
Reference frame
Problem statement:
Two particles with different masses collide elastically. Show that in the
centre-of-mass reference frame the final speeds of the two balls are the
same as before the collision.
Geosynchronous Orbits
One application of the law of gravity is to figure out how to put a satellite into orbit so
that it remains in the same position relative to ground all the time. A satellite in such a
position can be used to relay microwave communica

Work
1. A 250 kg crate is pulled 3.25 m along a rough horizontal plane using a horizontal
rope. The force of friction is 350 N while the tension in the rope is 1250 N.
a) Find the work done by each of the four forces and
