A 15-g ball is shot from a spring gun whose spring has a force constant of 600N/m. The spring can be compressed 5 cm. How high can the ball be shot if the gun is aimed vertically?
include a free body diagram. Be sure to label all forces with their agents and size. 1. A 5.0kg cat running along suddenly braces his furry feet on the slippery floot in order to stop.
While moving down the track at 10.0 m/s, you uniformly accelerate to 27.0 m/s in 10 s. Illustrate what is the average net force that you have applied to the car during the 10 s interval?
During a circus performance, a 70.3-kg human cannonball is shot out of an 15.4-m-long cannon. determine the average net force exerted on him in the barrel of the cannon
What is the magnitude of the acceleration caused by magnetic force? Ignore the gravitational force acting on the electron.
A light bulb at point x in the frame of reference O blinks on and off at intervals, ?t = t2 - t1. Use the expressions for the Lorentz transformations to derive the expression for the time dilation relations ?t and ?t'
Presume you carry a bag of groceries weighing 148 N from your car to the kitchen, a distance of 59m, without raising or lowering the bag.
A novice golfer on the green takes three strokes to sink the ball. The successive displacements of the ball are 4.00 m to the north, 2.00 m northeast, and 0.90 m at 35.0° west of south. begining at the same initial point, an expert golfer could ma..
What is the total negative charge, in coulombs, of all the electrons in a small 1.05{\rm g} sphere of carbon? One mole of C is 12.0{\rm g} , and each atom contains 6 protons and 6 electrons.
In a simple model of the hydrogen atom an electron orbits a proton at 2.18 x 10^6 m/s in a circle radius 5.29 x 10^ -11 m. Find the magnitude of the electron's angular momentum
suppose a large crate of 300kg is hung from a uniform steel beam of mass 100kg and 2 meters in length. what would be he initial angular acceleration of the beam
Using the data calculate the average speed of blood flow in the major arteries of the body which have a total cross-sectional area of about 2.0 cm2.
A 1 uF capacitor is charged when it is connected across a 9 V battery, Find the final charge and the voltage across the plates for the 1 uF and 2 uF capacitor
