esse Plot the Velocity/time graph 7 Estimate the distance moved Estimate the acceleration and déceleration d) Calculate the average speed 04 A train accelerates uniformly from rest to reach 54km/h in 200s after which the speed remains constant fro 300s. After 150s the train decelerates and later stopped a) Estimate the total distance moved b) Calculate the average speed Apply the equations of motion to calculate the distance moved Q5: a) A truck accelerates uniformly from rest fo 60km/h in 6 minutes after which the speed kee constant. Calculate the total time taken to travel 6km. The driver of the train shuts off the engine of the train and the train retards uniformly. I first 30s, the train covers 110m. The train comes to rest after the next 30s. Calculate the Initial speed of the train 11) Total distance the train moves before coming to rest Two cars are in a race. Car A starts from rest with uniform ncceleration of 0.6m/s. Car starts from rest, 4s later from the same and follows the same path with uniform accelera 0.9m/s". How far will the cars have gone when car B overtakes car A Q6a) An object moving at 60km/h slows down at 1.5m/s'.How long does it take to travel 70m as b) Two dogs initially standing at distance of 135m apart run towards each at 6.75m/s and 5.2 respectively. When they meet, how far are they from the point where the slower dog was s Projectile motion Q7 a) A bal is thrown vertically upward at speed of 40m/s, Calculate i. The greatest height reached li. Time taken to reach the ground iii. Its velocity after 3s iv. Distance moved after 3s b) An object is thrown vertically upward and retum to the ground 4 seconds later. Determine the maximum height reached ii. velocity with which its thrown upward 11. c) A parcel is dropped down a 16m deep shaft. Find the: i. time taken to reach the bottom of the shaft velocity of the parcel at the bottom of the shaft Q8 A bullet is fired at 800m/s from a gun positioned at 30° to the ground. Calculate t: a Horizontal and the vertical components of the velocity b) The horizontal displacement of the shell c) The maximum height the shell reaches d) The total time in air 09 Two marbles are placed on top ofl.2m high table. The first marble is kicked off the table at as 3.7m/s. The second marble drops off the table vertically down. a How far apart do the marbles land on the ground? b) What is the difference in time taken to reach the ground? OIO A projectile is fired with unknown velocity towards a 10m tall building at an angle of 40° level distance between the firing point of the projectile and the bottom of the building is 60m If the projectile hits the top edge of the building calculate the:
