2. A car accelerates along a straight road from rest to 90 km/h in 5.0s. What is the magnitude of average acceleration in meters per second squared. 3. If you are driving 110km/h along a straight road and look to the side for 2.0s, how far do you travel during this inattentive period? 4. At highway speeds, a particular car is capable of accelerating at about 1.8m/s?. At this rate, how long does it take to accelerate from 80km/h to...
A car moves on a flat road with initial velocity vector v1,x = 9.41 m/s and v1,y = -2.37 m/s, then accelerates for 6.53 seconds at an average acceleration of aav,x = -0.102 m/s2 and aav,y = 0.102 m/s2. What are the components of the car's final velocity, v2,x and v2,y? A) v2,x = B) v2,y = C) car's final speed =
x x + vt + ar A car is driving down a level highway at Vo = 60 mph (26.8 m/s) when suddenly it runs off an 8.0m high cliff a) Draw a good well-labeled diagram of this in the space below. Remember what well- labeled means. Show the velocity vector vo at the top of the cliff. Add a coordinate V, + x-x, (v + v)t dl) Find the rime of flight tyto the point at which the car...
