A rocket driven sled running on a straight, level track is used to investigate the physiological effects of rapid acceleration on humans. One such sled can attain a velocity of 1600 km/h in 1.8 s, starting from rest.
a. Assuming uniform acceleration, calculate the acceleration.
b. Express this acceleration in terms of g.
c. The last 2.00 km of track uses water brakes (a scoop that displaces water) to slow the rocket down. What is the acceleration of the sled if it stops at the end of the water brake zone?
A cylindrical barrel with a radius of 30 centimeter and a mass of 75 kilogram rolls across a warehouse floor without slipping. Calculate the total kinetic energy of the barrel
A die is selected at random from two twenty-faced dice on which the symbols 1-10 are written with non-uniform frequency as follows
A book is placed on a level floor. Is it true that the gravitational force (Fg) on the book by the earth and the normal force Fn on the book by the floor constitute an action-reaction force pair with Newton's 3rd law? Describe.
A 50.0-Ω resistor is connected to a 30.0-μFcapacitor and to a 60.0-Hz, 100-V (rms) source. Find the power factor and the average power delivered to the circuit
A diver 50m deep in 10C fresh water exhales a 1.2-cm-diameter bubble. What is the bubble's diameter just as it reaches the surface of the lake, where the water temperature is 20C? Suppose that the air bubble is always in thermal equilibrium with the ..
In the conduction equation Q = (kA?T)t/L, the combination of factors kA/L is called the conductance. By what factor can the body adjust the conductance
The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. What is the magnitude of the electric field within the cell membrane
A lab specimen is 15.2 mm from a converging lens. The image is 4.0 mm tall and 9.0 cm from the lens. How tall is the specimen?
A transformer is to be used to provide power for a computer disk drive that needs 6.6 V (rms) instead of the 120 V (rms) from the wall outlet. Find the number of turns in the secondary
A swimming pool has dimensions 32 m 9 m and a flat bottom. The pool is filled to a depth of 1.50m with fresh water. What is the force exerted by water on the bottom.
Find the equivalent resistances REQ1 and REQ2 in given Figure. Note that in calculating REQ2 the 33-kΩ resistor is connected to an open circuit and therefore does not affect the calculation.
A person takes a trip, driving with a constant speed of 89.5km/h except for a 22.0-min rest stop. If the persons average speedis 77.8 km/h, evaluate how much time is spent on the trip
