- A wheel accelerates from rest to 59 rad/s at a rate of 37 rad/s2. Through whatangle (in radians) did the wheel turn while accelerating?A) 59 rad, B) 94 rad, C) 47 rad, D) 38 rad4) A stone with mass m = 2 g at the end of a massless string is swinging in a circle of radius R = 1.8 m with and angular velocity ω = 11 rad/s. a) Write an expression for the velocity v of the stone. b) Calculate the velocity of the stone, v in m/s. c) In order to travel in a circle, the direction the stones path must constantly be changing (curving inward). This constant change in direction towards the center of the circle is a center pointing acceleration called centripetal acceleration ac. Write an expression for the centripetal acceleration ac of the stone, in terms of the linear velocity. d) Calculate the centripetal acceleration of the stone, ac in m/s².I need the answer as soon as possible
