A car initially travels north and then turns to the left along a circular curve. This causes a package on the seat of the car to slide toward the right side of the car. Which of the following is true about the net force on the package while it is sliding?
1. The force is directed away from the center of the circle.
2. The force is directed north.
3. There is not enough force directed north to keep the package from sliding.
4. There is not enough force tangential to the car’s path to keep the package from sliding.
5. There is not enough force directed toward the center of the circle to keep the package from sliding.
option 5 )
There is not enough force directed toward the center of the circle to keep the package from sliding.
if an object is in centripetal acceleration it experiences a net force towards center however in this case the packet moved away from center in the opposite direction that means there is no enough providing centripetal acceleration allowing the particle to be at rest and in uniform circular motion

A car travels around a curve with constant speed. The correct statement from the following is the car has an acceleration directed inward toward the center of the curve. the velocity of the car is constant. the car has an acceleration direction outward from the center of the curve. the car has zero acceleration. the car has an acceleration directed in the instantaneous direction of the velocity vector. A ball is whirled on the end of a...
Problem A car travels at a constant speed of 29.5 mi/h (13.2 m/s) on a level circular turn of radius 46.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, Aus, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body diagram (Fig. 7.13b) the normal direction is vertical and the tangential direction is into the page (step 2). Use Newton's...

answer all the above
the car has an acceleration directed in the instantaneous direction of the velocity vector. A ball is whirled on the end of a string in a horizontal circle at constant speed. Suddenly string breaks. Immediately after the string breaks, the ball will have a horizontal velocity away from the center of the circle have a horizontal velocity that is tangential to the circle. have a horizontal velocity toward the center of the circle. have a horizontal...
The force that causes an object to move in a circle is called the The centrifugal force The centripetal force There must be both centripetal and centrifugal force Nonsense! No force is required to cause an object to move in a circle Inertia A tin can on the end of a string moves in a circle because There is an unbalanced inward force acting on the can The can continuously pulls the string o Once the can starts moving its...
