A block rests on a horizontal frictionless surface. A string is attached to the block, and is pulled with a force of 45.0 N at an angle θ above the horizontal. After the block is pulled through a distance of 1.50 m, its speed is 2.60 m/s, and 50.0 J of work has been done on it. (a) What is the angle θ? (b) What is the mass of the block?
A 115 mCi radioactive tracer is made in a reactor. When delivered to a hospital 16 hours later its activity is 95 mCi. What is the tracer's half-life
an electron starts from one plate of a charged closely spaced vertical parallel plate arrangement with a velocity of
Two horses pull a large crate of negligible mass at constant speed across a barn floor by means of two light steel cables. What is the work done by each horse if the box is moved a distance of 30 m
What would be the final temperature of 100g of 16°C water when 107 g of 40°C iron nails are submerged in it? (The specific heat of iron is 0.12 cal/g °C. Here you must equate the heat gained by the water to the heat lost by the nails.)

At some point in its trajectory a ballistic missile (ICBM) of massm breaks into three fragments of mass m/3 each. Find the initial speeds of the latter two fragments in terms of v0
A light beam is traveling through an unknown substance. When it exits that substance and goes into air, the angle of reflection is 32.0°, What is the index of refraction of the substance
Two large identical flat metal plates are placed parallel to one another, seperated by a small distance compared to their linear size. One plate is given a charge per unit area 2.50E-5 C/m2 and the other a charge per unit area -2.50E-5 C/m2. Using..
A Carnot engine works between two heat reservoirs at temperatures Thot= 314.0 K and Tcold= 225.0 K. What is its efficiency? How much heat does it reject during each cycle
