Fifteen clowns are late to a party. They jump into their sportycoupe and start driving. Eventually they come to a level curve,with a radius of 27.0 meters. What is the top speed at which theycan drive successfully around the curve? The coefficient of staticfriction between the car's tires and the road is 0.800.

If on September fifteenth the north pole of the planet Earth istilted 15 degrees from the Sun.Rotation period of sun T= 27 daysand its axis points up. a)What would be the magnitude and directionof angular momentum vector (L) for this system at that exact day?b)How to find the moment of inertia (I in kg*m^2) of the Earthrotating on its axis at that day. c)How to find the ang. momentumfor Earth rotating on its axis (L in (kg*m^2)/s). d) What would bethe angular momentum vector of Sun rotating on its axis?. e) Whatwould be the total ang. momentum of the system?

I calculated the moment of inertia of earth and got I =9.72*10^37 kgm^2

Angular momentum of earth L=7.07*10^33 (kgm^2)/s
