Q. A stone with a mass of 0.800 is attached to one end of a string 0.700 long. The string will break if its tension exceeds 50.0 . The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed.Find the maximum speed the stone can attain without breaking the string.
Q. The minimum stopping distance for a car traveling at a speed of 30 {m/s} is 60 {m}, including the distance traveled during the driver's reaction time of 0.50 {s}.What is the minimum stopping distance for the same car traveling at a speed of 41 {m/s}?
Estimate mean and maximum velocities for a liquid
A child and sled with a combined mass of 49.20 kg slide down a frictionless hill that is 7.38 m high. If the sled starts from rest, what is its speed at the bottom of hill.
A 0.120 kg block on a horizontal frictionless surface is attached to the spring whose force constant is 572 N/m. The block is pulled from its equilibrium position at x = 0 m to a displacement x = +0.080 m and is released from rest. The block after th..
what would the period of the system be. When a particular mass-spring system is started by stretching the spring 5 cm, one complete oscillation takes 2 seconds.
Now consider this applet, where the two blocks have different masses. Plug the starting values into your formula from Part G, using 5 for mass of the red block and 10 for the magnitude of the acceleration of gravity.
A 100 g granite cube slides down a 40* frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 200g steel cube at rest. How high above the table must the granite cube be released to give the steel cube a spee..
