For the problem, identify all the forces acting on the object and draw a free-body diagram of the object. A skydiver has his parachute open and is floating downward through the air at a constant speed.

For the problem, identify all the forces acting on the object and draw a free-body diagram of the object. A box is being dragged across the floor at a constant speed by a rope pulling horizontally on it. Friction is not negligible.

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

For the problem, identify all the forces acting on the object and draw a free-body diagram of the object. You are driving on the highway, and you come to a steep downhill section. As you roll down the hill, you take your foot off the gas pedal. You can ignore friction, but you can't ignore air resistance.

An ascending elevator, hanging from a cable, is coming to a stop. Which forces are acting on the elevator? In which direction are those forces?

For the problem, identify all the forces acting on the object and draw a free-body diagram of the object. Your physics textbook is sliding across the table.

The motion of a very massive object can be minimally affected by what would seem to be a substantial force. Consider an oil supertanker with mass $3.0 \times 10 ^ { 8 } \mathrm { kg }$. Suppose you strapped two jets engines onto the sides of the tanker. Ignoring the drag of the water (which, in reality, is not a very good approximation), how long will it take the tanker, starting from rest, to reach a typical crusing speed of 6.0 m/s?

A 1500 kg car is traveling along a straight road at 20 m/s. Two seconds later its speed is 21 m/s. What is the magnitude of the net force acting on the car during this time?

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?

In t-ball, young players use a bat to hit a stationary ball off a stand. The 140 g ball has about the same mass as a baseball, but it is larger and softer. In one hit, the ball leaves the bat at 12 m/s after being in contact with the bat for 2.0 ms. Assume constant acceleration during the hit. a. What is the acceleration of the ball? b. What is the net force on the ball during the hit?

List three uses of the imperfect tense. a. _____ b. _____ c. _____

Mis padres fueron de paseo. (acercarse)
