- TOPIC: ACCELERATED MOTION How does the time affect the distance traveled by a body? What is your conclusion about accelerated motion?and How fast does the object end up moving at the end of the 2.22 s2.22 s? final speed of object:A rocket in outer space accelerates "to the left" at 18 m/s2for 30 seconds. Following the acceleration, the rocket is traveling at 490 m/s "leftward". What was its initial velocity? (I put "leftward" in quotes because there is no well-defined left and right, or up and down, in space.) (must show big six)

In going back, she increased her speed by 10 km/hr. If it took her a total of 10/3 hours, what was her original speed? Explain also. Create an expression to: Sarah traveled 90 km at a certain speed. Create another expression to: In going back, she increased her speed by 10 km/hr. Formula: v = d/tYou start your bicycle ride at the top of a hill. You coast down the hill at a constant of 4.0 m/s2. When you get at the bottom of the hill, you are moving at 25m/s, and you pedal to maintain that speed. If you continue at this speed for 1 minute, how far will you have gone from the time you left the hilltop?
