During 0.19 s, a wheel rotates through an angle of 2.42 rad as a point on the periphery of the wheel moves with a constant speed of 2.88 m/s. What is the radius of the wheel?

A highway curve with a radius of 800 m is banked properly for a car traveling 100 km/h. If a 1620- kg Porshe 928S rounds the curve at 220 km/h, how much sideways force must the tires exert against the road if the car does not skid?

v=rw w=2.42/0.19=12.74rad/s r=2.88/12.74=0.226m 2)Banking angle=v^2/rg=27.7^2/800g=61.1^2/rg r=(61.1/27.7)^2*800=3892m F=1620(61.1)(61.1)/3892=1554N

w=2.42rad/.19 sec= you do it.

speed=2.88m/s=wr=2.42/.19 * r

r= 2.88/(2.42/.19)
