A car starting from rest passes two successive milestones A and B that are 250 m apart. It takes 60 s to pass A and another 60 s to pass from A to B. Find the velocities of the car when it passes milestone A and milestone B. Assume that the acceleration of the car is uniform 

. (a) Find the change in wavelength of 80-pm x-rays that are

scattered 120° by a target. (b) Find the angle between the directions of the recoil electron and the incident photon. (c) Find

the energy of the recoil electron.

The position of a stone dropped from a cliff is described approximately by x = 5t^2 , where x is in meters and t is in seconds. The +x direction is downwards and the origin is at the top of the cliff. Find the velocity of the stone during its fall as a function of time t.

Show that if a generalized coordinate is cyclic then corresponding component of a generalized momenta is a constant of motion.

Using uncertainty principle show that an electron can't stay inside the nucleus . Radius of nucleas =5 ×10^-15

The gorilla, feeling exuberant, throws a 0.50kg banana straight up in the air from the ground with an initial energy of 30j. How high will the banana travel up?

Suppose two students measure the length of a piece of wire three times each. Student A obtains results of 8.09,

8.10, and 8.11 centimeters. Student B obtains determines a length of 8.1 centimeters for all of his three

measurements. Although the average length found for each student’s measurements was 8.1 cm, what

qualitative statements can be made concerning the measurements made by students A and B?
