6.) Astronauts visit a new planet called Melmac. On this planet, the astronauts weigh very little. An astronaut drops a wrench from a height of 1.5 m and it takes 7.2 seconds to hit the ground. What is the acceleration due to gravity on this planet in ft/sa? (Watch your units!) (ans: 0.19 ft/s) Use Kinematics Equations of Motion to find your answer.

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
