- Starting from a standstill, a windmill-style softball pitcher executed a pitch in 0.6 s. If her pitching arm is 0.75 m long and the tangential ball speed is 25 m/s, what is the magnitude of the total acceleration on the ball at this point?arrow_forwardIf 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)?arrow_forwardEven though an object can have a constant tangential speed, the acceleration of an object in circular motion can NEVER be ____________________. A. zero B. less than the value of the speed C. equal to the value of the centripetal force.arrow_forward
- A highway curve with radius R = 274 m is to be banked so that a car traveling v = 25.0 m/s will not skid sideways even in the absence of friction. At what angle should the curve be banked? What are the components of each force along these axes?arrow_forwardA 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.arrow_forward10 m/s, with 0.5 as the coefficient of static friction so that the car can still turn safely without skidding out of a curved road?arrow_forward
- 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.arrow_forwardAn aerobatic airplane flying at a constant 60.0 m/s makes a horizontal turn of radius 225 m. The pilot has mass 80.0 Kg. What is the pilot's apparent weight during the turn ?arrow_forwardIf the man pulls the strap with constant acceleration during a short time interval Δt, calculate the force (in Newtons) that he must exert in spinning up the disc. These are the numbers. Strap's final speed = v = 1.9 m/s. The disc's radius is R = 0.4 m The disc's mass is M = 2.4 kg The short time interval is Δt = 0.3 s The disc initially is non-rotating.arrow_forward
- A 50.0-kg child stands at the rim of a merry-go-round of radius 2.00 m, rotating with an angular speed of 3.00 rad/s. (a) What is the child’s centripetal acceleration? (Ans : 18.0 m/s2) (b) What is the minimum force between her feet and the floor of the carousel that is required to keep her in the circular path? (Ans : 900 N) (c) What minimum coefficient of static friction is required? Is the answer you found reasonable? In other words, is she likely to stay on the merry-go-round?
