Use the following information to answer parts a and b. A motorboat is travelling at its maximum speed of 6.0 m s⁻¹ straight across a river, which has a current of 3.8 m s⁻¹ downstream, as shown in the diagram The banks of the river are parallel to each other and straight. a) Calculate the velocity of the boat as seen by someone at the position marked ‘A’ on the diagram. b) If the river is 1100m wide, how long does it take for the boat to reach the other bank?
Explain why we only consider one dimensional motion when using a single motion sensor. Based on the definition of velocity, describe what you should observe in the velocity vs. time graph if you were measuring a stationary, distant object and you suddenly slid and object into the beam from the side [hint: think about the behavior of the position graph in this case.]
The motion of a cart can be represented by x(t)=(-2.5m/s)t-10.0m. At what time does this cart cross the origin? a)it crosses the origin t=4s after we start observing it b)It crosses the origin t=0s after we start observing it c)If it were moving the same way before we started observing it then it crossed the origin 4 seconds before we started counting.
Conclusion: Write a single paragraph describing the how the velocity of the car changes as time passes. Be sure to include your equation and the acceleration in your description.
Solve it correctly please. I will rate accordingly with multiple votes.
A car traveling at a speed of 25 m/s suddenly sees the red light 40 m ahead of him. The driver takes 0.75 s to react and slows the car down at a constant rate of 10 m/s2. 1. How long does it take the car to come to a complete stop from the moment the break was applied? 2. Find the total time the car takes to come to a complete stop from the moment the driver first saw the red light. 3. Determine whether the car ran the red light.
