Chapter P.2, Problem 25P
Additional Integrated Problems
A child’s sled has rails that slide with little friction across the snow. Logan has an old wooden sled with heavy iron rails that has a mass of 10 kg—quite a bit for a 30 kg child! Logan runs at 4.0 m/s and leaps onto the stationary sled and holds on tight as it slides forward. The impact time with the sled is 0.25 s.
a. Immediately after Logan jumps on the sled, how fast is it moving?
b. What was the force on the sled during the impact?
c. How much energy was “lost” in the impact? Where did this energy go?

1a)A 4.50 kg ball rolling north at 5.00 m/s collides with a 2.50 kg ball rolling south at 3.00m/s. If the collision is elastic, set up the equations you would solve to determine how fast is each ball moving after the collision.
1b)If the collision between the two balls in question (1a) instead results in both balls sticking together as one, what will their resulting velocity be?
A 60 g tennis ball with an initial speed of 31 m/s hits a wall and rebounds with the same speed. (Figure 1) shows the force of the wall on the ball during the collision.
What is the value of Fmax, the maximum value of the contact force during the collision?

- Scientists and engineers must interpret problems from various sources. We can practice this skill anytime we read a newspaper or magazine or browse the Internet. Consider the Rocket Car urban legend that can be found on many Internet sites, in which the Arizona Highway Patrol allegedly found the vaporized wreckage of an automobile. The story goes that after some analysis and investigation, it was believed that a former Air Force Sergeant attached solid-fuel rockets to his 1967 Chevy Impala and ignited the rockets approximately 3.9 miles from the crash site. The vehicle quickly reached a speed of approximately 275 mph. It continued at this speed for 20 to 25 seconds. The car remained on the highway for 2.6 miles before the driver applied the brakes. The brakes melted and the tires blew out, causing the vehicle to become airborne. It traveled through the air for 1.3 miles before it hit a cliff face 125 feet above the road. Of course, this story was debunked. It is physically implausible, but it can still provide an opportunity to practice analyzing a problem. a. C Draw a Sketch of the Situation. b. C For the constant-velocity part of the cars motion, identify initial and final positions, the velocity, and the time interval. c. N Calculate the displacement using the position data and then again using the velocity and time data. Are your results consistent? d. C If your results are not consistent, reread the legend and identify possible sources of the discrepancy.arrow_forward[3] Instructions: Solve the following problems. Express your final answers to two decimal places. 3. Two skaters collide and grab on to each other on frictionless ice.

It was the red van that blew out a red light. The two vehicles stick together as a result of the collision and slide at 16.0 m / s in a direction of 24.0o east of north. (See Figure 4) Calculate the speed of each vehicle before the collision. The collision occurs during a heavy rain storm; you can ignore the frictional forces between the vehicles and the wet road.

- Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Ball A is moving upward along the y axis at Va = 2.5 m/s and ball B is moving to the right along the x axis with speed Vb= 3.9 m/s. After the collision, assumed elastic, ball B is moving along the positive y axis ( Figure 1). What is the final direction of ball A? Express your answer using two significant figures. Answer should be in degrees. 0 = ________ degrees clockwise from the +y directionarrow_forwardObject B is at rest when object A collides with it. The collision is one-dimensional and elastic. After the collision object B has half the velocity that object A had before the collision. 1.) Which object has the greater mass? 2.) By how much is the mass of object B greater than that of object A? 3.) If the velocity of object A before the collision was 6.0 m/s to the right, what is its velocity after the collision?arrow_forwardA 4,700-kg truck runs into the rear of a 1,000-kg car that was stationary.

- There is a famous intersection in Kuala Lumpur, Malaysia, where thousands of vehicles pass each hour. A 750 kg Tesla Model S traveling south crashes into a 1250 kg Ford F-150 traveling east. What are the initial speeds of each vehicle before collision if they stick together after crashing into each other and move at an angle of 320 and a common velocity of 18 m/s. Draw a diagram and show all your work.arrow_forwardin Monkey and hunter case . my doctor want me to write a 5 lines about what I have learned from this screenshot. ( The simulation shows the classic physics situation of a monkey and hunter. In this case, the hunter is trying to tranquilize the monkey, so the monkey can be relocated to a better habitat. The monkey is clever—when the tranquilizer dart (in blue) leaves the gun, the monkey (in purple) lets go of the tree branch, and starts to fall straight down. Note that there is a net (not shown) at the bottom to catch the monkey, so the monkey won't get hurt.)arrow_forwardTwo motorcyle riders joined the trail bike riding. They were both excited since it was their first time participating in the said activity. As they were riding their motorcyle, an accident happened. Both riders lose their control. The first rider hit the concrete wall of the building while the second rider accidentally hit the csrnival's attraction, the bouncy castle. 1. Which rider do you think will be hurt more? Why? 2. Which rider will be safer? Why? 3. What type of collision happened in two motorcyle riders?arrow_forward
