A spacecraft lands on a newly discovered planet orbiting the star 51 Pegasi. To measure the acceleration from gravity on the planet, an astronaut drops a rock from a height of 2 m. A precision timer indicates that it takes the rock 0.71 s to fall to the surface. What is the acceleration from gravity on this planet?
A moving beltway at an airport has a speed 1 and a length L. A woman stands on the beltway as it moves from one end to the other, while a man in a hurry to reach his flight walks on the beltway with a speed of 2 relative to the moving beltway. (a) What time interval is required for the woman to travel the distance L? (b) What time interval is required for the man to travel this distance? (c) A second beltway is located next to the first one. It is identical to the first one but moves in the opposite direction at speed 1. Just as the man steps onto the beginning of the beltway and begins to walk at speed relative to his beltway, a child steps on the other end of the adjacent beltway. The child stands at rest relative to this second beltway. How long after stepping on the beltway does the man pass the child?
An athlete crosses a 25-m-wide river by swimming perpendicular to the water current at a speed of 0.5 m/s relative to the water. He reaches the opposite side at a distance 40 m downstream from his starting point. How fast is the water in the river flowing with respect to the ground? What is the speed of the swimmer with respect to a friend at rest on the ground?

The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 51 km/skm/s . To the crew's great surprise, a Klingon ship is 140 kmkm directly ahead, traveling in the same direction at a mere 30 km/skm/s . Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 6.7 ss . The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant.
3. A spacecraft flying in a straight line with velocity of 75 km/s fires its rocket motors for only 6.0 s. At the end of this time, its velocity becomes 120 km/s. Further, it travels with the same constant velocity. i) Find the distance travelled by the spacecraft in the first 10 seconds after the motors were started. ii) Calculate the average velocity of the travel of the spacecraft.
A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384000 km. Suppose it accelerates at an acceleration 20.0 m/s2 for the first time interval 15 min of the trip, then travels at constant speed until the last time interval 15 min , when it accelerates at 20.0 m/s2 , just coming to rest as it reaches the moon. What is the maximum speed attained? What fraction of the total distance is traveled at constant speed? What total time is required for the trip?

11. Cars A and B approached each other on a straight road from points 484 meters apart. A has an initial speed of 71 kph and is decelerating at the rate of 0.41 m/s^2. B has an initial speed of 25 kph and is accelerating at the speed of 0.33 m/s^2. At what time (seconds) will the cars be 229 meters apart from each other? Round off to two decimal places.
Lamborghini Murcielago is one of the most iconic cars ever as it was featured as a Batmobile in the third installment of Batman Trilogy directed by Christopher Nolan. If it can go from 0 to 60 miles per hour in 3 seconds, what is its rate of change in velocity per unit time? (1 mile is equal to 1.61 kilometers)
