A car and a motorcycle is racing from rest. The motorcycle first takes the lead because its constant acceleration am = 8.40 m/s2 is greater than the car's constant acceleration ac = 5.60 m/s2, but it soon loses to the car because it reaches its greatest speed vm = 58.8 m/s before the car reaches its greatest speed vc = 106 m/s. (20=7+5+8 points)
a. How long does the car take to reach the motorcycle?
b. How far have the motorcycle and car travelled from the initial point, when the car catches the motorcycle?
c. Draw the graph of position versus time for both car and motorcycle for 0 < t < 20 s.
At one instant a bicyclist is 53m due east of a park's flagpole, going due south with a speed of 12m/s. Then 37s later, the cyclist is 53m due north of the flagpole, going due east with a speed of 12m/s. For the cyclist in this 37s interval.
what speed does boxcar have after 10 seconds.What is the object's displacement Dx.
Starting from rest, a 98 kg firefighter slides down a fire pole. The average frictional force exerted on him by the pole has a magnitude of 800N, and his speed at the bottom of the pole is 3.2 m/s. How far did he slide down the pole.
A bug crawls outward from the center of a compact disc spinning at 160 revolutions per minute. The coefficient of static friction between bug's sticky feet and disc surface is 1.10.How far does the bug get from the center before slipping.
Use graphical techniques to find out the direction of the dog’s resultant displacement vector. Give the direction of the resultant displacement in degrees (out of 360).
Two metal spheres, each weighing 24-kg are placed 0.05 m apart. Compute the magnitude of the gravitational force the two spheres exert on each other.
A broken piano emits frequencies from a low of 32.0 Hz to a high of about 4100 Hz. What is the shortest wavelength if the speed of sound in air is 342.50 m/s? Record the answer to three decimal places and include units in the answer.
In deep space two spheres each of radius 5.00 m are connected by a 3.00 x 10^2 m nonconducting cord. If a uniformly distributed charge of 35.0 mC resides on the surface of each sphere, calculate the tension in the cord.
Two friends, Al and Jo, have a combined mass of 164kg. At the ice skating rink, they stand close together on skates, at rest and facing each other.
Compute what resolving power is needed to measure with a spectrograph the natural line width of the alpha particles from Po-212
Explain the distinction between reimbursement grants and entitlements. Explain how does this distinction affect the way each type of grant is accounted for?
A novice skier, starting from rest, slides down a frictionless 37.0° incline whose vertical height is 175 m. Explain how fast is she going when she reaches the bottom?
