If the car is accelerating at 15 ft/s² at the instant r = 2500 ft determine the required angular acceleration light at this instant. Express your answer in radians per square second to three significant figures. • View Available Hint(s) vec ?

Question 2: The wheel starts from rest with an angular velocity of @=0.20², 0 is in radian. Determine the magnitude of the linear acceleration of point P after the wheel has turned 1 revolution. r=0.5 m P (a) 9.92 m/s² 31.2 m/s² (b) (c) 32.7 m/s² (d) 45.2 m/s²

In the crank mechanism shown, if the arm AB rotates counterclockwise with angular velocity = 3 rad/s and angular acceleration = 4 rad/s2, determine the speed and acceleration of piston C at the instant shown. %3D 6m 5m

A pendulum with a cord of length r = 1.05 m swings in a vertical plane (see figure). When the pendulum is in the two horizontal positions 0 = 90° and 0 = 270°, its speed is 4.95 m/s. a (a) Find the magnitude of the radial acceleration (in m/s2) for these positions. m/s2 (b) Find the magnitude of the tangential acceleration (in m/s?) for these positions. m/s? (c) Draw a vector diagram to determine the direction of the total acceleration for these two positions.
