Exam 6: Applications of Newtons Laws

You push downward on a trunk at an angle 25° below the horizontal with a force of If the trunk is on a flat surface and the coefficient of static friction between the surface and the trunk is 0.61,what is the most massive trunk you will be able to move?

During a hockey game,a puck is given an initial speed of 10 m/s.It slides 50 m on the horizontal ice before it stops due to friction.What is the coefficient of kinetic friction between the puck and the ice?

A 600-kg car is going around a banked curve with a radius of 110 m at a steady speed of 24.5 m/s.What is the appropriate banking angle so that the car stays on its path without the assistance of friction?

An object attached to a spring is pulled across a horizontal frictionless surface.If the force constant (spring constant)of the spring is 45 N/m and the spring is stretched by 0.88 m when the object is accelerating at What is the mass of the object?
