1. You attach a force scale to a toboggan resting in the snow. a) What is the minimum value of static frictional force and under what conditions would you observe that value on your force scale? b) What two (equal in magnitude and opposite in direction) forces is the scale measuring when you start to pull on the toboggan but it remains stationary? Be specific. c) What happens to the number on the force scale as you start to pull on the toboggan but it remains stationary? Explain. d) What happens to the toboggan if your applied force exceeds the maximum static frictional force? e) What happens to the number on the force scale in the moment the toboggan starts to move? Explain. f) What two (equal in magnitude and opposite in direction) forces is the scale measuring when you pull on the toboggan and it moves at a constant speed. Be specific. 2. The coefficient of static friction between a toboggan and dry snow is 0.50. If the toboggan’s mass is 9.75 kg, what is the minimum applied force required to move the toboggan?
1. You attach a force scale to a toboggan resting in the snow.
a) What is the minimum value of static frictional force and under what conditions
would you observe that value on your force scale?
b) What two (equal in magnitude and opposite in direction) forces is the scale
measuring when you start to pull on the toboggan but it remains stationary? Be
specific.
c) What happens to the number on the force scale as you start to pull on the
toboggan but it remains stationary? Explain.
d) What happens to the toboggan if your applied force exceeds the maximum static
frictional force?
e) What happens to the number on the force scale in the moment the toboggan
starts to move? Explain.
f) What two (equal in magnitude and opposite in direction) forces is the scale
measuring when you pull on the toboggan and it moves at a constant speed. Be
specific.
2. The coefficient of static friction between a toboggan and dry snow is 0.50. If the
toboggan’s mass is 9.75 kg, what is the minimum applied force required to move the
toboggan?
