The catapult of the aircraft carrier USS Abraham Lincoln accelerates an F/A-18 Hornet jet fighter from rest to takeoff speed of 173 mi/h in a distance of 307 ft. How much time does it take for the fighter to accelerate to takeoff speed?

As a science project, you drop a watermelon off the top of the Empire State Building, 320m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 33.0 m/s How fast is the watermelon going when it passes Superman?

A juggler throws a bowling pin straight up with an initial speed of 9.7 m/s from an initial height of 2.8 m. How much time elapses until the bowling pin returns to the same initial height?

The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans and animals. When grown in a uniform medium rich in salts and amino acids, these bacteria swim along zig-zag paths at a constant speed of 20 μm/s. Figure shows the trajectory of an E. coli as it moves from point A to point E. Each segment of the motion can be identified by two letters, such as segment BC. a. For each of the four segments in the bacterium’s trajectory, calculate the x- and y-components of its displacement and of its velocity.b. Calculate both the total distance traveled and the magnitude of the net displacement for the entire motion.c. What are the magnitude and the direction of the bacterium’s average velocity for the entire trip?

A baseball player hits a homerun during a game. The ball leaves his bat at 27 degrees with a speed of 17 m/s. The ball soars into the upper deck 200 m from home plate. The ball takes 3.5 s to reach the upper deck. How high above the ground did the ball land?

A hockey puck slides off the edge of a table with an initial velocity of 20.0 m/s. The height of the table above the ground is 2.0 m. What is the magnitude of the velocity of the puck just before it touches the ground?

A ball is thrown vertically downward from the top of a 70 m tall building with an initial speed of vi = 3.6 m/s. How long will it take the ball to reach the ground?

A small rock is thrown vertically upward with a speed of 22.4 m/s from the edge of the roof of a 39.5 m tall building. The rock doesn't hit the building on its way back down and lands on the street below. Ignore air resistance. (a) What is the speed (in m/s) of the rock just before it hits the street? (b) How much time (in sec) elapses from when the rock is thrown until it hits the street?

A mischievous caracara sees a fisherman unscrew a shiny steel nut from a bolt on his ship while doing repairs in a harbor off the Falkland Islands. The fisherman watches helplessly as the bird picks up the nut and flies toward the shore. The bird flies due east at a constant speed of 5m/s and constant height of 11m . The bird flies directly over a person on the shoreline, dropping the nut at the instant they are above the person. Prepare: Once the nut has been released, in which directions does the acceleration vector have components along?

A hot-air balloon of diameter 12 m rises vertically at a constant speed of 15 m/s . A passenger accidentally drops his camera from the railing of the basket when it is 15 m above the ground. If the balloon continues to rise at the same speed, how high is the railing when the camera hits the ground?
