At one particular moment, a 15.0 kg toboggan is moving over a horizontal surface of snow at 4.80 m/s. after 7.00 s have elapsed, the toboggan stops. use a momentum approach to find the magnitude of the average friction force (in n) acting on the toboggan while it was moving

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
