A car is skidding to a stop on a level stretch of road. Identify all the action/reaction pairs of forces between the car and the road surface. Then draw a free-body diagram for the car.

For the problem. Draw a motion diagram, a force identification diagram, and a free-body diagram. You've slammed on the brakes and your car is skidding to a stop while going down a $20 ^ { \circ }$ hill.

You hold a picture motionless against a wall by pressing on it. Draw a free-body diagram.

Your Car Is Skidding To A Stop From A High Speed. Draw a free-body diagram of the car; Suppose that the car moving on the right; Draw the vectors starting at the black dots. The location and orientation of the vectors will be graded: The length of the vectors will not be graded.

A box is being dragged across the floor at a constant speed by a rope pulling horizontally on it. Friction is not negligible.

For the problem, identify all the forces acting on the object and draw a free-body diagram of the object. Your car is skidding to a stop from a high speed.

A cannonball has just been shot out of a cannon aimed $45^{\circ}$ above the horizontal. Drag cannot be neglected.

Your car is accelerating to the right from a stop. Identify all forces acting on the object and draw the free-body diagram. Draw the force vectors with their tails at the dot. The orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded. The $4$ forces are:

• Normal Force
• Weight
• Drag
• Force of Friction on the car

two children fight over a 200 g stuffed bear. The 25 kg boy left with a 17 N force. Ignore all other forces on the bear (such as its weight). a. At this instant, can you say what the velocity of the bear is? If so, what are the magnitude and direction of the velocity? b. At this instant, can you say what the acceleration of the bear is? if so what are the magnitude and direction of the acceleration?

A constant force is applied to an object, causing the object to accelerate at $8.0 \mathrm{~m} / \mathrm{s}^2$. What will the acceleration be if

The force is doubled?

Mentioned figure shows an object's acceleration-versus-force graph. What is the object's mass?

A car skids to a halt to avoid hitting an object in the road. Draw a motion diagram of the car from the time the skid begins until the instant the car stops.

A baseball pitcher throws a $100 \mathrm{mph}$ fastball to batter Brandon Bopp. Bopp hits a $450$-foot home run out of the park. When the ball contacts the bat, which force was greater: the force of the ball on the bat or the force of the bat on the ball?

Your car is skidding to a stop at a high speed.
