The traffic light turns red, the driver accelerates forward with aĬonstant magnitude of 2.25 m/s2 for 3.70 s. In order to pass through an intersection before A car is traveling north along a straight road with a constantĪ car is traveling north along a straight road with a constant.
c) Prepare a scaled time-distance traveled graph. b) Prepare a scaled time-acceleration graph.
Problem 4 A car travels along a straight road at a speed of 20 m/s, it decelerates uniformly to a stop over a period of 30 seconds the car then it travels in the opposite of the original direction accelerating uniformly to a speed of 30 m/s in that direction over a period of 15 seconds a) Prepare a scaled time-velocity graph. Problem 4 A car travels along a straight road at a speed of 20 m/s, it.At this same instant car C is traveling along the straight road with a speed of 30 m/s while decelerating at 3 m/s?.Determine the velocity = 100 m 3 m/s 30° and acceleration of car A relative to car C. 45 25 m/s 1.5 m/s Car A travels along a straight road at a speed of.Ĥ5 25 m/s 1.5 m/s Car A travels along a straight road at a speed of 25 m/s while accelerating at 15 m/s.The bus traveled for 6 hours at an average speed of 60miles per hour. How long did it take her to run the race? Time 12 km Time = 3 km/hr 12 kilometers 12 km 3 km/hr 3 km/hr = 4 hours Distance Speed Time=Ħ The bus traveled for 6 hours at an average speed of 60miles per hour Susan ran a 12 km race at an average speed of 3km/hr. What is the average speed of a snail that travels 10 meters in 2 hours? Speed 10 meters Speed = 2 hours 10 meters 10 meters 2 hours 2 hours = 5 m/hr Distance Time Speed=ĥ Susan ran a 12 km race at an average speed of 3km/hr When you cover up the letter of what you are trying to find, the formula to find it will reveal itself! Remember… Average = Total ÷ Total Speed Distance TimeĢ The tool we use to help us solve for speed, distance or time is a formula triangle that we call “D-Street.” The D stands for Distance The S stands for Speed The T stands for Timeģ To use “D-Street,” you cover up the letter that stands for what you are trying to solve for, or what you are trying to find out.
