A 124.6-kg object is dropped from a height of 3.8m above a spring with a constant of 14235.8N/m. How much (in cm) will the spring be compressed?
What is the angular displacement of a 0.7m diameter wheel that rolls 3m clockwise?
The pressure of fixed mass of gas is 960 mm Hg when the volume of the is 3.0 m^3. Find the pressure of the gas when its volume is 4.5 m^3 l. Assume that the pressure is constant.
The velocity of sound in a gas of pressure p and density roll is written as v=kp^xp^y find x and t and state the relationship
How much work must be done to accelerate an 800kg car from 15m/s to 30m/s?
A 0.1kg ball starts from rest and rolls 5.8m down a short ramp so that it drops 1.8m vertically. Calculate the speed of the ball at the bottom of the ramp
Hey, Hope your having a great day! Can you list 3 or more physical and social outputs on industrial evolution?
A robin of mass 110g speeds up from 12.3 m/s to 15.4 m/s in level flight. Calculate how much work is done by the robin on its mass
Water is driven through an horizontal pipe at constant pressure (pi). The pipe has a constriction
along its length. At places where the pipe becomes narrower, the pressure p2 at that location
satisfies:
a. p1 = p2
b. p1>p2
C. p1<p2
d. It is possible for p, may be either higher than, lower than or equal to p2 .

and released. What is the maximum speed obtained by the mass?
