Chapter 3, Problem 53AP
Review. The biggest stuffed animal in the world is a snake 420 m long, constructed by Norwegian children. Suppose the snake is laid out in a park as shown in Figure P3.39, forming two straight sides of a 105° angle, with one side 240 m long. Olaf and Inge run a race they invent. Inge runs directly from the tail of the snake to its head, and Olaf starts from the same place at the same moment but runs along the snake. (a) If both children run steadily at 12.0 km/h. Inge reaches the head of the snake how much earlier than Olaf? (b) If Inge runs the race again at a constant speed of 12.0 km/h. at what constant speed must Olaf run to reach the end of the snake at the same time as Inge?

The world's largest stuffed animal is a 420-meter-long snake built by Norwegian children. Assume the snake is laid out in a park, as shown in the figure below, forming two straight sides of a 115° angle, one side being 340m long. Olaf and Inge compete in a race they devise. Inge runs directly from the snake's tail to its head, while Olaf starts from the same place but runs along the snake. How much faster does Inge reach the head of the snake than Olaf if both children run steadily at 15.0km/h?
SVS is running an outdoor skills competition. The race is
made up of three different events that involve a swim, a
climb, and a zip line. You begin at point S. The finish is at
point F, which is 200m from S in a direction 65° north of
west. The first part of the race is a 600m swim to an island,
B, due west of S. The second part is a climb up a vertical
cliff to point C. Point C is at an angle of elevation of 10°, as
seen from point S. The third part is a zip down a zip line
from point C to the finish at point F. You can swim at 1.5m/s,
climb at 0.75m/s, and zip at 15m/s.

- In 1780, in what is now referred to as “Brady’s Leap,” Captain Sam Brady of the U.S. Continental Army escaped certain death from his enemies by running horizontally off the edge of the cliff above Ohio’s Cuyahoga River, which is confined at that spot to a gorge. He landed safely on the far side of the river. It was reported that he leapt 22 ft across while falling 20 ft. Tall tale, or possible?a. What is the minimum speed with which he’d need to run off the edge of the cliff to make it safely to the far side of the river?b. The world-record time for the 100 m dash is approximately 10 s. Given this, is it reasonable to expect Brady to be able to run fast enough to achieve Brady’s leap?arrow_forwardA commuter airplane starts from an airport and takes the route shown in Figure P3. 19.

- You are assigned to do some calculations for a movie stunt that involves a car on a straight road. The road, pictured above, has a hill that rises 8.0 m above the flat region. The top of the hill is a circular arc of radius 20 m. You need to determine whether a car traveling under certain conditions will lose contact with the road at the top of the hill. There is a stop sign 50 m from the beginning of the hill. You are to assume that a car of mass 1600 kg accelerates uniformly from rest at the stop sign, has a speed of when it reaches the beginning of the hill, and then coasts with the engine off. Assume energy losses due to friction and air resistance are negligible. Calculate the magnitude of the acceleration of the car during the first 50 m. Calculate the time it takes the car to reach the beginning of the hill. Calculate the magnitude of the net force required to accelerate the car during the first 50 m.arrow_forwardUse the component method to add the vectors A and B shown in Figure P3.9.

- Q2. A drone is used to spray pesticide in a farm. It covers (d1=30 m) towards south. Then it flies (d2=40 m) in a direction 350 east of south, then by changing its direction it covers a distance of (d3=50m) in the direction 650 east of north and finally it covers a displacement (d4=65m) in a direction of 300 south of west. Calculate total displacement (d) covered by the drone and its direction.arrow_forwardGordon likes to take his dog for a walk on the beach each morning. The beach near his home is quite large, so he can park his car on it. He has a routine that he likes to stick to. Gordon parks his car at a point C that is 34◦ west of south of a point L where the lifeguard sits. He then walks in a straight line from his car to L. Next, he changes direction and walks due south along the shoreline in a straight line for 1200 metres until he reaches a large rock R, where he turns again and heads straight back to his car, which is 740 metres from the large rock. (You may assume that the beach is flat and all distances are measured in a straight line.) (iii) Find the distance between Gordon’s car and the lifeguard.
