A point on a rotating turntable 20.0 cm from the center accelerates from rest to a final speed of 0.700 m/s in 1.75 s. At t = 1.25 s, find the magnitude and direction of (a) the radial acceleration, (b) the tangential acceleration, and (c) the total acceleration of the point.
5For the case of myoglobin, where mnet =4000 g/mole, how fast does a centrifuge have to spin before the bottom of the tube at a radius of R1 = 20 cm has 10 times the concentration at a radius of R2 = 19.9 cm? Find ω in radians per second from the formula, divide by 2π to get revolutions per second, and then multiply by 60 to get rpm (revolutions per minute).
Consider that the car is making a flat circular curve with radius R = 230 m. Knowing that the friction coefficient between the tires and the road is = 0.960, determine the maximum speed with which the car can turn without sliding. Adopt: g = 10.0 m / s ^ 2.
A cyclist On & circular track of radius r = 240 m is traveling at 8 m/s His speed in the tangential direction (i.e, the direction of his travel) increases at the rate of 1 m/s?. What Is most nearly the cyclist's total acceleration? (A) -0.9 m/s? (B) 0.7 m/s? (C) 0.9 m/s? (D) 1.0 m/s?
If you are driving at a German motorway at 262 km/h, what radius of curvature (in m) of a curve is needed, if the acceleration should be limited to g≈10 m/s^2 (assuming uniform rotational motion)?
One way to create artificial gravity in a space station is to spin it. If a cylindrical space station 350 m in diameter is to spin about its central axis, at how many revolutions per minute (rpm) must it turn so that the outermost points have an acceleration equal to g? Express answer in revolutions per minute.
A planet orbits a star, in a year of length 3.51 x 107 s, in a nearly circular orbit of radius 3.92 x 1011 m. With respect to the star, determine (a) the angular speed of the planet, (b) the tangential speed of the planet, and (c) the magnitude of the planet's centripetal acceleration.
The moon orbits the earth at a distance of 3.84 x 10^8 m with a tangential speed of 1 km/s. If the moon's mass is 7.3 x 10^22 kg, fiind the Moon's: a) acceleration (magnitude and direction) b) net force (magnitude and direction)
In uniform circular motion, the net force is perpendicular to the velocity and changes the direction of the velocity but not the speed. If a projectile is launched horizontally,the net force (ignoring air resistance) is perpendicular to the initial velocity, and yet the projectile gains speed as it falls. What is the difference between the two situations?
Engineers who design roads typically “bank” (incline) curves in such a way that a car traveling at the recommended speed does not have to rely on friction between its tires and the road in order to round the curve. Suppose the radius of curvature of a road segment is 50 m, and the recommended speed is 40 km/hr. At what angle should the curve be banked?
A rock is spun in a sling at a constant speed of 56.0 m/s. What rate of rotation, in rev/s, is necessary to give the rock the required speed? Take the radius of the circle to be 1.75 m.
The Moon orbits the Earth at a distance of 3.84 x 10^8 m and with a tangential speed of 1 km/s. If the Moon’s mass is 7.3 x 10^22 kg, find the Moon’s a) acceleration (magnitude and direction) b) net force (magnitude and direction)
