A 20 g bullet traveling at 159 m/s is fired into a 0.413 kilogram wooden block anchored to a 99 N/m spring. Assuming no friction, to the nearest thousandth of a meter, determine the amplitude of the resulting motion? And, to one decimal place, determine what is the angular frequency?
A 54g ice cube can slide without friction up and down a 33 degree slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 11cm . The spring constant is 25 N/m When the ice cube is released, what distance wil..
A brick is initially 7.72 cm high and an aluminum can is initially 7.73 cm high. By how much should their temperatures be raised in order for the brick and the can to have precisely the similar height?
What was the arrow's initial speed. A small sphere with a mass of 2.00×10^-3g and carrying the charge of 4.80×10^-8C hangs from a thread near a very large, charged insulating sheet. The charge density on the sheet is -2.90×10^-9C/m^2 .
