Please help!
A young girl with mass 42.5kg is sliding on a horizontal, frictionless surface with an initial momentum that is due east and that has magnitude 94.0kg * (m/s) . Starting at 0s , a net force with magnitude F=( 8.10N/s )*t and direction due west is applied to the girl.
Part B
How much work has been done on the girl by the force in the time interval from t= 0s to the time calculated in part A?
Express your answer with the appropriate units.
Part C
What is the magnitude of the acceleration of the girl at the time calculated in part A?
Express your answer with the appropriate units.
