Q1. A ferris wheel has the maximum height of 256 feet and a wheel diameter of 230 feet. Find an equation for the wheel if center of the wheel is on the y-axis.
Q2. A person driving her car at 44.00 km/h approaches an intersection just as the traffic light turns yellow. She knows that the yellow light lasts only 2 s before turning to red, and she is 30 m away from the near side of the intersection. The intersection is 15 m wide. Her car's maximum deceleration is -5.20 m/s2, whereas it can accelerate from 44km/h to 70km/h in 7.8 s. overlook lengths of her car and her reaction time.
when a dime (diameter 1.624 cm) is placed straight over it, bubble can be seen by looking down into the cube. What are upper and lower bounds of the range of the possible depths of the air bubble beneath surface.
Find the energy, in joules, of one quantum of energy for an atomic oscillator in a block of aluminium.

A 7.40-nC charge is positioned 1.70 m from a 4.80-nC charge. (a) Find the magnitude of electrostatic force that one particle exerts on the other. (b) Is the force attractive or repulsive.
A steel ball of mass M is released from rest at point P. It follows a smooth curved rail to point Q and finally reaches point R with K.E. of 7J. The speed of the ball at point Q is 2MS-1 and the height between point P and the ground is 3m. Then find ..
Therefore of his observations, Ole Roemer concluded that eclipses of Io by Jupiter were delayed by 22 min throughout a six-month period as the Earth moved from the point in its orbit where it is closest to Jupiter to the diametrically opposite point ..
A ball is thrown from the top of a building upward at an angle of 39degrees to the horizontal and with an initial speed of 24m/s. The ball is thrown at a height of 57 m above the ground and hits the ground 98.55 m from the base of the building. Wh..
Driving in your car with a constant speed of 13 m/s, you encounter a bump in the road that has a circular cross section, as indicated in the figure. If the radius of curvature of the bump is r = 29 m, find the apparent weight of a 59-kg person in you..
The electric field points radially outward at all points within the sphere (and outside too, for that matter). What is the strength of the electric field at a distance r from the center, inside sphere.
If the charge of the point charge in the figure were -2Q (instead of +Q), by what factor would the magnitude of the force on the point charge due to the dipole change.
What is the frictional force
