5, Some of the funniest videos on the web involve motorists sliding uncontrollably on icy roads. Here let's compare the typical stopping distances for a car sliding to a stop from an initial speed of 10.0 m/s on a dry horizontal road, an icy hori- zontal road, and (everyone's favorite) an icy hill. (a) How far does the car take to slide to a stop on a hori- zontal roadi if the coefficient of kinetic friction is = 0.60, which...

A box with mass m = 1.2kg on an inclined frictionless surface is released from rest from a height h = 1.75 m. After reaching the bottom of the incline the box slides with friction (uk = 0.25) along a horizontal surface until coming to a rest after a distance d. 1. Draw a free body diagram for the box while it is on the incline. Clearly label all forces with standard names. 2. Draw a free body diagram for...

[2] A block with mass ma is placed on an inclined plane with slope angle α and is connected to a second hinging block with mass ma > ma by a massless cord passing over a small frictionless pulley (see figure). The coefficient of kinetic friction between mass mA and the incline is negligible. Initially the masses are at rest, with mass mA at the bottom of the incline and mass mg a height h above the table supporting the...

At an amusement park, a car of mass m rolls without friction around a track as shown. The car starts from rest at point A, a height h = 3R above the bottom of the loop (R is the radius of the loop). Treat the car as a point-like particle. (a) Draw the free body diagram for the car and find the car’s kinetic energy and normal force acting on the car at the top of the loop (point B)....

You visit a swimming pool with a 3.6-m-long waterslide that is inclined at 30 degree below the horizontal plane. You decide to test Newton's second law by predicting the time interval it will take you to move down the slide starting at rest. Complete the table that follows to make your prediction. Sketch the situation described in the problem: provide all known information. Draw a free-body diagram for the system object. Label the forces. Make sure the diagram is consistent...

The 1800-kg car descends a hill of angle 0 3°. The drag force due to air resistance is k 0.45 kg/m D kv2 for Use the sketch to complete a free-body diagram. From an initial velocity of 29 m/s (65 mph), the car coasts 1600 m along the slope. Determine the velocity at that point Hint: After finding the acceleration, choose a dr vs dvs to integrate the kinematics; the resulting integral simplifies with the substitution, u = denominator, which...
