A car enters a level, unbanked, semicircular hairpin turn of 100-m radius at a speed of 28 m/s. The coefficient of friction between the tires and the road is μ = 0.800. If the car maintains a constant speed of 28 m/s, it will

gans

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

conservation of mass

mass before something happens = mass afterwards
