Answer to Question #83299 in Classical Mechanics for Bianca
a) calculate the value of N, the normal contact force
b) calculate the speed at which the car is travelling
The answers are below but i couldn't figure out to get to them.
a) 9.5x10^3 N
The Newton’s second law gives
N=mg/cosθ =(1000×9.8)/cos〖15°〗 =10146 N
v= √(gR tanθ )=√(9.8×200×tan〖15°〗 )=23 m/s
