- What can you say about the velocity- time graph of an object moving with constant accelerated motion?While driving on the highway at 100 km/hr, a billboard distracts you for 2.5 seconds. How far does your car travel in this time? Please answer this question in metersIf the top acceleration of the raging bull is 73 mph, using the equation for speed to compute how long it takes the ride to travel to Madison, WI from its location in Gurnee, IL, if the track was connected all the way to Madison, WI?
- What does an inspection of the velocity-versus-time graph show?why do we use meters “per” second when calculating speed?Your speed meter shows that your driving 60kph, and you want to overtake a truck running 50kph, 10m ahead of you. If your vehicle can accelerate at 0.10m/s^2, how much time do you need to overtake? write your solution on paper a. 3s b. 4.3s c. 3.4s d. 4s
- If Cathy and Myra take 2.0 h to walk from their house to their school at a rate of 1.0m/s, how far is their school from the house?For an object which is constantly accelerating, what would the appropriate Velocity versus Time graph look like?Consider the velocity vs. time graph of a person in an elevator shown in Suppose the elevator is initially at rest.It then accelerates for 3 seconds, maintains that velocity for 15 seconds, then decelerates for 5 seconds until it stops. Theacceleration for the entire trip is not constant so we cannot use the equations of motion from Motion Equations for ConstantAcceleration in One Dimension for the complete trip. (We could, however, use them in the three individual sections whereacceleration is a constant.) Sketch graphs of (a) position vs. time and (b) acceleration vs. time for this trip.
- The Elco Voltmeter company has a robot part delivery system that moves at a speed of 3 ft/s. The path that the robot follows from the stock room through the assembly area is 780 ft in length. How much time in seconds is required for the robot to travel in its path?The bus stop is 540m from martins location and the bus arrives in 3 mins to that stop. How fast will he have to travel more to reach the bus just in time?A fireworks shell has a constant acceleration from rest to a velocity of 68 m/s over a distance of 9.5 m. How long, in seconds, does the acceleration last? And calculate the acceleration, in meters per second squared. Please explain how you got your answer in detail.
