1. A 1400 kg car goes around a corner with a radius of curvature= 60m.

a) if the coefficient of static friction between the tires and the roads is 0.800 what is the maximum speed the driver can go before skidding. the curve is unbanked/flat.

2. A 2.40kg uniform rod of length of .750m rotates about its center. At t=0, its angular speed =2.50 rad/sec. It smoothly increases its rotation rate with an acceleration a=1.50 rad/s^2

a) what is its angular speed at t=6.50 seconds

b) how many radians would a spot on the rod have gone during those 6.50 seconds

c) what is the linear speed at t=6.50 seconds at the spot at the end of the rod

d) find the force that would need to be applied tangentially to the end of the rod have this acceleration
