Question

A car goes around a curve a 15 m/s. The radius of the curve is50m. Calculate the centripetal acceleration of the car. What is the gravitational force between a teacher of mass 90kgand a student of mass 60kg when the student sits in the front rowof the classroom, 2m from the teacher?

Explanation / Answer

1) ac= v2/r =152/50= 4.5sec-1 2) Fgrav= G*M1*M2 /r^2= 6.673*10^(-11)*90*60/2^(2)=.00000009N Hope this helps, Coobreez
