4. Marlene, a 45.4kg girl is running at 3.5m/s on a pier from the shore towards a lake. At the edge of the pier she jumps onto a raft in the water. The raft was originally drifting towards the pier with a drift speed of v= -1m/s. What is the speed of Marlene and the raft if the mass of the raft is 112kg ?

A meter stick is held vertically above your hand, with the lower end between your thumb and first finger. On seeing the meter stick released, you grab it with these two fingers. You can calculate your reaction time from the distance the meter stick falls, read directly from the point where your fingers grabbed it. Q: If the measured distance is 17.0 cm, what is the reaction time?
3. A baseball is thrown upward from the top of Otto Hahn (which is 7 floors high) with an initial speed of 18 ft/s. Mr. Nakset who is on the 7 floor sees it pass by as it falls to the ground. If one floor is ten feet high and the eye level of Mr. Nakset is 5 feet from the floor, how many seconds have passed from when it was released to when Mr. Nakset saw it?
you are traveling in a car at some specified speed limit. You see a car moving at the same speed coming toward you. How fast is the car approaching you, compared with the speed limit? My guessed answer is that same speed as the specifiec speed limit but not sure. Could you clarify?
Dev Your college quadrangle is 82 meters long and 69 meters wide. When you are late for class, you can walk (well, run) at 6 miles per hour. You are at one corner of the quad and your class is at the directly opposite corner. How much time can you save by cutting across the quad rather than walking around the edge?

Q2: Gun sights are adjusted to aim high to compensate for the effect of gravity, effectively making the gun accurate only for a specific range. (a) If a gun is sighted to hit targets that are at the same height as the gun and 100.0 m away, how low will the bullet hit if aimed directly at a target 150.0 m away? The muzzle velocity of the bullet is 275 m/s. (b) Discuss qualitatively how a larger muzzle velocity would affect this problem and what would be the effect of air resistance.
1. At time t in seconds, a particle's distance s(t), in micrometers (μm), from a point is given by s(t) = e^t-1. a.Suppose you want to approximate the instantaneous velocity at t=2 using average velocities. Describe, in a complete sentence or two, why average velocities over smaller time intervals yield better approximations.
A meter stick is held vertically above your hand, with the lower end between your thumb and first finger. When you see the meter stick released, you grab it with those two fingers. You can calculate your reaction time from the distance the meter stick falls, read directly from the point where your fingersgrabbed it. (a) Derive a relationship for your reaction time in terms of this measured distance, d. (b) If the measured distance is 17.6 cm, what is your reaction time?
A student writes, "A bird that is diving for prey has a speed of -10 m / s." What is wrong with the student's statement? What has the student actually described? Explain.
Unreasonable Results Suppose you wish to shoot supplies straight up to astronauts in an orbit 36,000 km above the surface of the Earth. (a) At what velocity must the supplies be launched? (b) What is unreasonable about this velocity? (c) Is there a problem with the relative velocity between the supplies and the astronauts when the supplies reach their maximum height? (d) Is the premise unreasonable or is the available equation inapplicable? Explain your answer.
Light travels at a speed of about 3 103 m/s. (a) How many miles down a pulse of light travel in a time interval of 0.1 s, which is about the blink of an eye? (b) Compare this distance to the diameter of Earth.
