2. A motor boat starts from rest on a lake and accelerates in a straight line at a constant rate of 3.0ms^-1 for 8s. What distance does the boat cover during this time? 3. A boy standing on a platform throws a ball straight up with an initial velocity of 11.2ms^-1

2. The distance covered by the boat can be calculated using the equation of motion: Given that the acceleration is and the time is , we can substitute these values into the equation: So, the boat covers a distance of 96 meters during this time.3. The maximum height reached by the ball can be calculated using the equation of motion: Given that the initial velocity is and the acceleration due to gravity is , we can substitute these values into the equation: So, the maximum height reached by the ball is 6.4 meters.
