1) An electron is shot through a magnetic field (see above) with an initial velocity of 100 ft/sec. The magnetic fieldaccelerates it in the perpendicular (normal) direction with a constant acceleration of 1000 ft/sec2. If the magnetic field has a depth of one foot,
i) how long does it take the electron to traverse the field
ii) how much is the deflection from the straight path through the field?
2) A daredevil stunt rider is attempting to jump a stack of automobiles from a 20 deg (?) ramp as illustrated below. If he leaves the ramp at 60 mph, how long will he be in the air? How far will his horizontal jump be? What will be his highest elevation? If his jump angle is increased to 30deg, will he stay in the air longer? Is his horizontal jump longer? Is this vertical maximum higher?
a single cycle of a ramp function of voltage versus time has the form vt 100t from -0.01 to 0.01 s. using direct

A rotating saw blade has 48 teeth and 4 slots. If the room where the saw is used is illuminated with a pulsed light source, at what pulse frequencies will The saw blade teeth appear to be stationary?
An ideal Otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 540R and 2400R.
A direct injection, four-stroke, six cylinder Diesel engine has 10L if displacement volume. Bore and stroke dimensions are 125mm and 136mm, respectively. The engine was designed to deliver 184 HP at 2100 RPM. Calculate the air flow rate (g/s) when pi..
A heat engine operates between reservoirs at 1000 and 300 K. Some of the power output from the heat engine drives a refrigerator which operates between 250 and 300 K. The heat-transfer input at 1000 K to the heat engine is 1000 kJ, and the heat trans..
