Question

3. I am driving at 20.0 m/s when (at time t 0 a car pulls out onto the road, 50.0 meters ahead of me. I immediately start to brake, slowing down at 3.0 m/s. Meanwhile the other car, which started at rest, accelerates at 2.0 m/s At-4.0 s, I have slowed down to 8.0 m/s and the other car has sped up to 8.0 m/s; in those first four seconds I have moved 56.0 m and the other car has moved 16.0 m. Both cars continue accelerating as before until t = 5.0 s (a) Sketch a graph of the velocities of the two cars from t 0 to t = 5 s. Put the velocities of both cars on the same set of axes, and label which is which. (b) Sketch a graph of the positions of the two cars fromt 0 tot 5s. Again, put the positions of both cars on the same set of axes, and label which is which. Pay particular attention to what the graphs look like near t- 4 s (c) Do we ever collide?

    Elvis is in a speeding car moving in the trajectory x(t) = (40 m/s)t along the x axis and t is the time in seconds. An Elvis fan is moving in the trajectory x(t) = −400 m − (20 m/s)t + (4 m/s^2 )t^2 . Sketch the initial positions of Elvis and the fan’s car in an appropriate coordinate system. Find the time at which the fan’s car has zero instantaneous velocity, v(t) = 0. Find when Elvis and the...

    A probe has been launched vertically from the surface of Mars. At time t 0, it has reached a height of y1,0 320 m, and is moving upward at vy10 80 m/s when its engines cut out. At the same moment, the mother ship is y20 1500 m from the Martian surface, moving down directly toward the probe at 25 m/s and slowing down at the rate of 0.80 m/s2. On the surface of Mars, the gravitational acceleration is gMars-3.72...

    020 (part 1 of 3) 10.0 points You are driving at the speed of 34.8 m/s (77.862 mph) when suddenly the car in front of you (previously traveling at the same speed) brakes and begins to slow down with the largest deceleration possible without skid- ding. Considering an average human reaction, you press your brakes 0.576 s later. You also brake and decelerate as rapidly as possible without skidding. Assume that the coefficient of static friction is 0.722 between both...

    Busy car wash Suppose you run a between time 0 and time s > 0 is a Poisson process with rate A = 1. The number of red cars that come to the car wash between time 0 and time s > 0 is a Poisson process with rate 2. The number of blue cars that come to car wash between time 0 and time s >0 is a Poisson process with rate 3. Both Poisson processes are independent of...
