A 60-kg (including the passenger) sled is subject to a net force of 20 N pushing in the direction of the sled's motion as it is moving over a horizontal surface for a distance of 11 m after having started from rest. At this point the sled is released as it starts down a 10.0° incline. However, the snow is not very deep, and the sled stops after having moved an additional 35 m. What is the work
done by friction while the sled is on the incline? a. –3.6E+3 J b. –3.8E+3 J c. –3.4E+3 J d. –2.0E+4 J
A boy on a bicycle approaches a brick wall as he sounds his horn at a frequency 400.00 Hz. The sound he hears reflected back from the wall is at a frequency 408.00 Hz
At what is the speed is the boy riding his bicycle toward the wall? Assume the speed of sound in air is 340 m/s. A) 3.68 m/s B) 333 m/s C) 6.67 m/s D) 6.80 m/s E) 3.37 m/s
Recall that a raisin cake is sometimes used to imagine how an expanding universe behaves. Suppose you are in a uniformly expanding raisin cake, sitting on Raisin A, looking at Raisin B, 2 cm away from you
Raisin B is moving away from you at 1 cm/sec. At the same time, you observe another Raisin C, which is moving away from you at 3 cm/sec. How far away is Raisin C from Raisin A? A) 6 cm B) 3 cm C) 2/3 cm D) 3/2 cm E) impossible to say
