A car starting from rest speeds up to 55 m/s with a constant acceleration of 4.5 m/s^2, runs at this speed for a time, and finally comes to rest with deceleration of 8.5 m/s^2. If the total distance travelled in 800 m. 1. Find the distance covered during acceleration in m 2. Find the distance traveled at constant speed 3. Find the total time of travel Use 3 decimal places for the final answer, DO NOT round off during calculation. Do not include units in the final answer.

The figure shows a train traveling at a constant uniform velocity of 75 kph and a car travelling at a speed of 36 kph towards point 0. A. Which of the following gives the nearest value of the acceleration of the car, if the car reaches point 0, 10 seconds ahead than that of the train. B. If the train moves at a uniform velocity, which of the following gives nearest value of the required time for the train to reach the point 0. C. Using the acceleration computed, which of the following gives the value of the velocity of the car at the collision point.

In the figure below, if the motor turns gear A with an angular acceleration of 82 rad/s2. The angular velocity of gear D is
