1. Starting from point a, a car travels 200 M to the east and then comes back to point8 and 10 seconds. What is the average velocity of the car during the entire motion? 2. The graph of position x versus time t for certain objects motion is a straight line with a negative slope. What kind of motion of the object undergoing ? 3. A ball is hit at 15 M/S at 40 above the horizontal. What is the vertical speed of the ball at the initial point of its motion?What is the vertical speed of the ball at its highest point ? A car with an initial speed of 30 M/S to the right slows down with deceleration of 5M/S^2 for four seconds . It done speeds up to the same direction with constant acceleration of 2M/S squared until it reaches a speed of 16 M/S. By drawing a diagram of the entire motion of the car showing coordinate axes on applying kinematics equations. 1. Determine the velocity of the car at time T=4 seconds. 2. Determine the net displacement of the car during the entire motion. 3. Determine the average velocity of the car during the entire motion. 4. Sketch, a velocity versus time graph for the entire motion of the car. A stone is thrown vertically upward with a speed of 15 M/S from the edge of a cliff of height 95 m. Ignore air resistance. 1. Using the upward direction positive and using kinematics equation, determine the velocity with which it strikes the base. 2. Using the upward direction positive determine the position of the stone at 2. three seconds after it was thrown upward from the top of the cliff. A plane flies in a directions 20 west of north for 800 km displacement D1 , from airport A airport B. The plane then departs from airport B heading in a direction 40 south of west for 300 km displacement, D2 to airport C. 1. Draw and determine using a ruler and protractor the result displacement magnitude, and direction of the plan using tail to tip method of vector addition. 2. Calculate the resultant displacement, both magnitude and direction of the plan, using the component method using calculations of vector addition. A projectile is shot from the edge of a cliff, unknown height at an initial velocity 80 M/S at an angle 30 above X axis . After 10.0 seconds, the projectile alarms on the ground at a distance, ask away from the base of the cliff. 1. Draw diagram, showing the projectile path, starting from the edge of the cliff to the ground show launching velocity factor with the components and landing velocity factor with that component. 2. Determine the height of the cliff 3. Determine the horizontal distance, ask, traveled by the projectile 4. Determine the maximum height reached by the projectile. Food supplies drops from an airplane when the airplane was 230 m above the ground and was traveling at 156 KM/H in the horizontal direction. 1. Try the diagram of the projectile path of the supplies starting from the point of released to the ground. 2. Using downward direction, positive Y and using kinematics equation, determine the time for the food supply to land on the ground on horizontal distance travel during this time
