Shown in the figure below is a block and track system. All locations indicated by solid black lines are frictionless. The region indicated by the tan hash is a patch of friction with coefficient k = 0.255. A = 0.43 meters. After the mass leaves the spring it climbs small block of mass m = 0.89 kg is initially compressed against a spring. The spring constant is k = 103.9 N/m and the initial compression is X1 0.54 meters and eventually slides to a stop after entering the frictional patch. up the hill of height y3 = 4 V3=? 3 m (stopped) (1) V₂=? friction d=? m (2) Уз ▼ X1 Calculate all the following: The velocity of the mass after it leaves the spring but before it climbs the hill, v₂ = m/s The velocity of the mass at the top of the hill, V3 = m/s The distance the mass slides onto the frictional area, d = meters
In an amusement park ride, riders stand against the vertical wall of a spinning cylinder. The floor falls away and the riders are held up by friction. If the radius of the cylinder is R, find the minimum number of revolutions per time necessary if the coefficient of friction between a rider and the wall is given.
A carnival ride has people stand inside a vertical cylinder with their backs to the wall. The cylinder starts spinning and the riders find that they are “stuck” to the wall and don’t slide down, even if the floor is removed. The ride has a radius of r. The person has a mass of m and is moving with a constant speed of v. The coefficient of static friction between the person and the wall is μs , and kinetic friction μk. The person is only touching the wall, not touching the floor. What is the magnitude of the acceleration of the person? In what direction does it point? The speed is constant. Why is the acceleration not zero? Briefly explain. No equations!
