3. As two trains move along a track, their conductors suddenly notice that they are headed toward each other. The below figure gives their velocities v as functions of time t as the conductors slow the trains. The figure's vertical scaling is set by vş = 40.0 m/s. The slowing processes begin when the trains are 200 m apart. What is their separation when both trains have stopped? 40 m v (m/s) IN I 4 6t(s)

Joe decides to race his younger sister, Debbie, and gives her a 25 m head start. At the instant Joe starts running, his sister reaches a velocity of 12 m/s [W] while accelerating at 0.4 m/s2 [W]. If Joe accelerates at a rate of 1.2 m/s2 [W], how long does it take for him to catch up to his sister?
On a straight 1.0 km track, a race car accelerates from rest to its top speed through 325 m [W] at 3.5 m/s2. The car then decelerates at a rate of 1.9 m/s2 [E] to a complete stop. Will the car stop before the track ends?
A bottle rocket is shot straight up in the air with a speed 30 m/s. if the air resistance is ignores, the bottle would go up to a height of approximately 46 m. however the rocket goes up to only 35 m before returning to the ground. What happened? Explain, giving only a qualitative response.
Gayle runs at a speed of 4.00 m/s and dives on a sled, initially at rest on the top of a frictionless, snow-covered hill. After she has descended a vertical distance of 5.00 m. her brother, who is initially at rest, hops on her back, and they continue down the hill together. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 50.0 kg, the sled has a mass of 5.00 kg, and her brother has a mass of 30.0 kg.
If a spacecraft is launched from the Moon at the escape speed of the Earth, how fast will the spacecraft be going when it is very far away from the Moon, ignoring the effects of other celestial bodies?
A Nordic jumper goes off a ski jump at an angle of 10.0 below the horizontal, traveling 108 m horizontally and 55.0 m vertically before landing. (a) Ignoring friction and aerodynamic effects. calculate the speed needed by the skier on leaving the ramp. (b) Olympic Nordic jumpers can make such jumps with a jump speed of 23.0 m/s, which is considerably less than the answer found in pan (a). Explain how that is possible
s Type A nerve fibers in humans can conduct nerve impulses at speeds up to 140 m>s. (a) How fast are thenerve impulses in miles per hour? (b) How far (in meters) can theimpulses travel in 5.0 ms?
A ball rolled 12.0 m [E] in 10.0 s, hit an obstacle, and rolled straight back. After the collision, the ball rolled 8.00 m [W] in 6.00 s. What was the average velocity of the ball?
Scientists have investigated how quickly hoverflies start beating their wings when dropped both in complete darkness and in a lighted environment. Starting from rest, the insects were dropped from the top of a 40-cm-tall box. In the light, those flies that began flying 200 ms after being dropped avoided hitting the bottom of the box 80% of the time, while those in thedark avoided hitting only 22% of the time.a. How far would a fly have fallen in the 200 ms before it began to beat its wings?b. How long would it take for a fly to hit the bottom if it never began to fly?
3.13 A car comes to a bridge during a storm and finds the bridge washed out. The driver must get to the other side, so he decides to try leaping it with his car. The side the car is on is 20.6 mm above the river, whereas the opposite side is a mere 1.9 mm above the river. The river itself is a raging torrent 60.0 mm wide. 1.How fast should the car be traveling just as it leaves the cliff in order to just clear the river and land safely on the opposite side?2.What is the speed of the car just before it lands safely on the other side?
