Towns A and B in Figure P3.35 are 80.0 km apart. A couple arranges to drive from town A and meet a couple driving from town B at the lake, L. The two couples leave simultaneously and drive for 2.50 h in the directions shown. Car 1 has a speed of 90.0 km/h. If the cars arrive simultaneously at the lake, what is the speed of car 2?

- A movie stunt is designed such that the stuntman is to run across and directly off a rooftop onto the roof of the next building, which is 3.6 m below and 5.9 m away from the building the stuntman runs on. a. How long does it take for the stuntman to fall to the same height as the roof of the shorter building? b. Can the stuntman successfully make the jump if he runs at 4.8 m/s?arrow_forwardYour car is parked at the high school. After school you take off and travel for 27 km towards lowa City. At this point, you realize you forget your wallet and travel back to Tipton for 15 km before you find your wallet was just on the floor. You turn back and head towards low city for 36 km. What is your displacement?arrow_forwardA rocket leaves its platform with acceleration ⃗ a= ( 4.00 ^i+2.00 ^j ) m/s2 and initialvelocity v0= ( 8.00 ^i+12.0 ^j ) m/s for 5.00 seconds. After this 5.00 second interval, the rocket’sengines are turned off, and the rocket then travels as a projectile.a. Determine how long the rocket is in the air.b. What is the rocket’s velocity vector (in unit-vector notation) just before it hits theground?arrow_forward
- A stone is thrown vertically upward with an initial velocity of 3 m/sec from the top of a tall building. The stone strikes the ground 4 second later. a. What is the maximum height reached by the stone above the building? Ans. S = 0.459 m b. What is the height of the building? Ans. H = 66.331 m c. What is the velocity of the stone as it strikes the ground? Ans. V = 36.20 m/secarrow_forwardA person travels by car from one city to another with different constant speeds between pair of cities. She drives for 30 min at 80 km/hr, 12 min at 100 km/hr and 45 min at 40 km/h and spends 15 min eating lunch and buying gas a. Determine the average speed for the trip b. Determine the distance between the initial and final cities along the route. O 52.9 km/hr. 90 km O45 km/h, 110 km O78 km/h, 60 kmarrow_forwardWhy is the following situation possible? Emily challenges her friend David to catch a $1 bill as follows. She holds the bill vertically as shown in figure P2.29 with the center of the bill between but not touching David's index finger and thumb. Without warning, Emily releases the bill. David catches the bill without moving his hands downwards. David reaction time is equal to the average human reaction time. Avg human reaction time is .2s. Dollar bill is approx 15.5cm in length. I need help explaining this. Thank you.arrow_forward
- A stone is dropped from a balloon at an elevation of 300 m. Two seconds later, another stone is projected vertically upward from the ground with a velocity of 75 m/sec. a. When will the stones pass each other? Ans. t = 4.963 sec b. Where will the stones pass each other from the ground? Ans. S = 179.2 m c. Compute the time travelled by the stone from the ground until they pass each other. Ans. t2 = 2.96 sec Please indicate the formula and what to find given value.arrow_forwardA Honda Civic Automobile is moving at 6 m/sec and accelerating at 1.50 m/sec2 to overtake a passenger bus which is 115.2 meters ahead. If the passenger bus is moving at 18 m/sec and decelerating at 0.9 m/sec2, a. how soon will the Honda Civic Automobile pass the passenger bus? b. how far will each vehicle have travelled ( Honda & Bus respectively)?arrow_forwardEmily throws a soccer ball out of her dorm window to Allison, who is waiting below to catch it. Emily throws the ball at an angle of 30° below horizontal with a speed of 12 m/s, and Allison catches it 2.5 s later. How far from the base of the dorm does Allison stand to catch the ball, in metersarrow_forward
- An Olympic diver is on a diving platform 5.20 m above the water. To start her dive, she runs off of the platform with a speed of 1.3 m/s in the horizontal direction. What is the diver's speed, in m/s, just before she enters the water? m/sarrow_forwardAn Osprey can fly horizontally (not diving) at a maximum speed of 70.0 km/hr. The bird takes off from rest at the edge of a cliff, heading east, and accelerates at a rate of 1.21 m/s2. a. How long does it take to reach top speed?b. How far does it travel during this amount of time?c. Once the hawk has reached its top speed, it turns 29 degrees to the south and flies at constant speed for another 25 seconds. How far is it from the cliff at the end of its initial take off?arrow_forwardYou are driving along Lawrence Ave. to speed up to try to make it through the intersection before it turns red (poor decision!). Your car accelerates at 1.3 m/s?. You reach the light after accelerating for 4.3 seconds. What is your speed at the light in m/s? 60 km/h. You see the traffic light ahead is still green and decide V, =v, +aAt A: Pictorial Representation Sketch showing events, describe events, coordinate system, label givens & unknowns with symbols, conversions B: Physics Representation Motion diagram, motion graphs, velocity vectors, events a +x t t C: Word Representation Describe motion (no numbers),-assumptions, estimated result (no calculation) D: Mathematical Representation Describe physics of steps, complete equations, algebraically isolate, substitutions with units, final statement of prediction E: Evaluation Answer has reasonable size, direction and units?
