A 2.30-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 3.40sin (2pi*t), where F is in newtons and t is in seconds. The force constant of the spring is 35.0 N/m.
In an effort to stay awake for an all-night study session, a student makes a cup of coffee by first placing a 200 W electric immersion heater in 0.320kg of water.
The femur is a bone in the leg whose minimum cross-sectional area is about 4.5 x 10-4 m2. A compression force in excess of 7.7 x 104 N will fracture this bone. Bone has a compression Young's modulus of 9.4 x 10^9 N/m2
Paul is what most people consider a "jock." He is the captain of both the football and wrestling team and he also plays hockey. Upon entering Mrs. Title's class she figured that he would not take course seriously nor would he excel in class. She p..
If the parachutist comes to rest with constant acceleration over a distance of 0.610 m, what force does the ground exerts on her.
A pendulum of length 9.00 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 3m. (That is, 3.0 m is no longer free to swing.) How long does this pendulum take for one o..
A wave on a string is described by D(x,t) = (1.2 cm)sin[2 pi (x/(3.9 m) + t/(0.4 s) + 1)], where x is in m and t is in s. What is the wave number
A carpenter is driving a nail into a board. The 1.25 kg hammer moves at 8.85 m/s when it strikes the nail. What is the change in length of the nail
A small glass bead has been charged to + 30{\rm nC}. What is the magnitude of the acceleration of a proton that is 3.0{\rm cm} from the center of the bead
A 68.0 kg person escapes from a burning building by jumping from a window 25m above a catching net. Assuming that air resistance exerts a 95N force on the person during the fall, determine the person's velocity just before hitting the net.
