Q. An object-spring system oscillates with amplitude of 3.00cm. If the spring constant is 205 N/m and object has a mass of 0.50 kg, determine each of the following values.
(a) The mechanical energy of the system
your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.
(b) The maximum speed of the object
your response differs from the correct answer by more than 10 percent. Double check your calculations.
(c) The maximum acceleration of the object
Note the gravitational acceleration of equatorial sea level is g = 32.0088ft/s^2 and that its variation is 0.003ft/s^2/ 1000ft ascent. find the height in miles above its point for which g = 30.504 ft/s^2 and what is the weight of a 180lb man on top o..
At one instant a bicyclist is 75m due east of a park's flagpole, going due south with a speed of 13.0 m/s. Then, 10s later, the cyclist is 65 m due north of flagpole, going due east with a speed of 20.0 m/s.
A Carnot engine performs work at the rate of 380 kW when using 730 kcal of heat per second. If the temperature of the heat source is 560 C, at what temperature is the waste heat exhausted.
Dan is gliding on his skateboard at 4 m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 6 m/s (as measured by an observer on the ground). Dan's mass is 50 kg and the skateboard's mass is 7 kg. How fast is Dan going..
What is the net force exerted by these two charges on the third charge = 46.5 placed between and at = -1.235 ? Your answer may be positive or negative, depending on direction of the force.
A major-league pitcher can throw a baseball in excess of 44.2m/s. If a ball is thrown horizontally at this speed, how much would it drop by the time it reaches the catcher who is 16.10 m away from the point of release.
Calculate the magnitude of the electric field at one corner of a square 1.43
What is the breaking strength
A gymnast with mass m1 = 47 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 118 kg and length L = 5 m. Each support is 1/3 of the way from each end. Initially the gymnast stands at the left end ..
Compute the magnetic flux
Three charges, +q, +2q, and +4q, are linked by strings (Assume that the middle charge is fixed in space and the other 2 charges are held there by the tension alone.)
Sketch complete free body force diagrams for each crate. A person with his ear to the ground sees a huge stone strike the concrete pavement a moment later 2 sounds are heard from an impact one travels in the air and the other in concrete.
