An 9.00 rm kg point mass and a 15rm kg point mass are held, Ask an Expert

Academics

Q1. An Olympic skier moving at 31.0 m/s down a 15? slope encounters a region of wet snow of coefficient of kinetic friction μ = 0.56.

The acceleration of gravity is 9.80 m/s2.

How far down the slope does she travel before coming to a halt?

Reply in units of m

Q2.An 9.00 {rm kg} point mass and a 15{rm kg} point mass are held in place 50{rm cm} apart. A particle of mass m is released from a point between the two masses 19{rm cm} from the 9{rm kg} mass along line connecting the two fixed masses.
