Q1. An 80 g, 35 cm long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 13 g ball of clay travelling horizontally at 2.50 m/s hits and sticks to the very bottom tip of the rod.
To what maximum angle, measured from vertical, does the rod (with attached ball of clay) rotate?
Q2. A car travels at 105 km/h on a level road in the positive direction of an x axis. Each tire has a diameter of 67.70 cm. Relative to a woman riding in the car and in unit-vector notation, what are the velocity at (a) center, (b) top, and (c) bottom of the tire and the magnitude a of the acceleration at (d) center, (e) top, and (f) bottom of each tire? Relative to a hitchhiker sitting next to the road and in unit-vector notation, what are the velocity at (g) center, (h) top, and (i) bottom of the tire and the magnitude a of the acceleration at the (j) center, (k) top, and (l) bottom of each tire?
Question: Field and force with three charges? What is the electric field at the location of Q1, due to Q 2 ?

Assume, instead, that the observer had been moving away from Earth with a speed of 0.80c. How much time would observer have measured for the car to be filled in this case.
A 2.00-m tall basketball player is standing on the floor 10.0 m from the basket. If he shoots the ball at a 30 degree angle from the horizontal, at what initial speed must he throw the ball so that it goes through the basket without striking the back..
What is the focal length of this mirror. If the object is 25 cm in front of the mirror, what is the image distance.
A 2.0-C charge moves with a velocity of (2.0i + 4.0j + 6.0k) m/s and experiences a magnetic force of (4.0i - 20j + 12k) N. The x component of the magnetic field is equal to zero. Find out the y component of the magnetic field.
The magnitude of the vector is 45.0 units and points in the direction 386 counter clockwise from the positive x-axis. Calculate the x-component of this vector.
Illustrates the difference between acceleration and velocity
