Question

A car is rounding a flat, unbanked curve of constant radius, with constant speed. The direction of the force of friction is in the direction opposite the velocity in the direction of the velocity towards the center of the curve radially outward Question 2 3 pts Two identical boxes are on the same rough horizontal surface. Box 1 is pushed by a horizontal force and is moving to the right at constant speed. Box 2 is pushed by a different horizontal force and is moving to the right, specding up Which is true? The friction force on box 1 is the same as the one on box 2 The friction force on box 1 is smaller than the one on box 2. The friction force on box 1 is langer than the one on box 2 We need to know the magnitude of the pushing force to determine which frictional force is larger

Explanation / Answer

Question 1

Answer :towards the center of the curve.

Explanation:

When moving on an unbanked curved road then the only force that can provide centripetal force is friction and it acts towards center of the curve.

Question 2:

Answer:The friction force on box 1 is same as that on box 2.

Explanation:

Both the boxes are in motion so force acting on them is kinetic friction. Now as both are identical and and on same rough surface so kinetic friction is same for both as kinetic friction only depends on normal force and surfaces in contact.
