Train B leaves 1 hour later, in the opposite direction, with a speed of 200 km/h. a) How long will it take to get there? b) Where will they meet? c) How much distance does each one travel? 2. The displacement of a particle from an origin is given by where t is the time in seconds. i. Find expressions for the velocity and acceleration. ii. Find the velocity after 2 seconds. 3. Find the displacement when the acceleration is 16ms-2.
