Question

III. 1. A bus accelerates uniformly from rest to a moderate velocity and then maintains its velocity until it reaches the school and decelerates uniformly until it stops. Illustrate the motion of the multicab using velocity-time graph 2. Consider the following velocity-time graphs below and find the displacement of the moving object v (m/s) 30 25 20 15 10 5 0 5 10 15 20 25 t (s) 3. A stone is dropped from the top of a cliff. It hits the ground below after 8.5 s. How high is the cliff? 4. If a ball rolls gently ($v_0$=0) off a vertical cliff, how long does it take to reach 90 km/h? a) Determine the time it takes for a rock to fall from a height of 105 m starting from rest. b) What is its initial velocity? 5. A ball is thrown nearly straight up into the air with a speed at 35 m/s from the ground. a) How high does it go? b) How long is it in the air? c) What is the velocity of the ball at its maximum height?
