Algebra.Com's Answer #383423 by lwsshak3(11628)![]() ![]() ![]() You can put this solution on YOUR website! Convert the linear velocity (25 km/hr) of a car going around a round-about to angular velocity in rad/s. Assume the radius of the circle the car is travelling is 10 m. \n" ); document.write( "** \n" ); document.write( "By qualitative analysis method: \n" ); document.write( "(25km/hr)(1000m/km)(hr/3600 sec)(rev/2πr(m)(2π rad/rev) \n" ); document.write( "km, hr, m, rev, 2π cancel out, leaving: \n" ); document.write( "25*1000/3600r≈.694 rad/sec \n" ); document.write( "same answer you got \n" ); document.write( " |
