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?
Which one of the following describes an object in motion? (2.1) (a) A period of time has passed. (b) Its position is known. (c) It is continuously changing position. (d) It has reached its final position.
Speedy Sue, driving at 30.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 155 m ahead traveling at 5.00 m/s. Sue applies her brakes but can accelerate only at 2.00 m/s2 because the road is wet. Will there be a collision? State how you decide. If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sues car and the van.

In April 1974, Steve Prefontaine completed a 10.0 km race in a time of 27 min, 43.6 s. Suppose "Pre" was at the 7.29 km mark at a time of 25.0 min. If he accelerated for 60 s and then maintained his increased speed for the remainder of the race, calculate his acceleration over the 60 s interval. Assume his instantaneous speed at the 7.29 km mark was the same as his overall average speed up to that time.acceleration = ? m/s2
