Consider the system described in the example with m1 = 0.51 kg and m2 = 0.40 kg. The coefficient of static friction between the block and the surface is 0.45. The angle ? of the force F is equal to 27.2°. IfF = 0, you can easily show that the block will accelerate to the left since the maximum static friction force is not sufficient to keep the block at rest. If F is sufficiently large, it is clear that the block will accelerate to the right. Find the range of F that allows the system to remain at rest.
The ramp is inclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.800, and the log has an acceleration of 0.800 m/s2. Find out the tension in the rope.
One way to decrease your use of fossil fuels is to heat your water via solar radiation. A solar water heater runs cold water through dark, radiation absorbing tubing.
Because of air resistance a constant torque exerted on the system to keep it spinning at that rate. Assuming that the air exerts a miniscule force on the stick (but a significant force on the ball), identify the force the air exerts on the ball.
