Linear motion 01 A car moving at 100kmh apply breaks and stops in a distance of 80m. Calculate: a) The retardation b) Breaking time The distance covered during the first 2s after applying breaks 02 the data below is for distance moved by train and the time elapsed 0 0 20 Sim 50 40 50 4 14 0 10 6 2. to) b) c) Plot the distance time graph Use the data in a) to plot the speed time/graph Estimate the average speed 03 the data below is for velocity of the car and the time elapsed 5 10 20 30 Vem tist 4 8 2. 6 0

Plist the Velocity time grape Estimate the distance moved Beate the accization and déceleration Cacciate the average speed Ata accelerates only for rest to reach 54 in 200s after which se speed rains constant to 300s. After 150s the train decelerates and Estimate the total distance moved Calate the average speed Sely the ecuations of motion to calculate the distance Loved Asock accelerates only for rest to 60 bin benutes afier which the speed keeps constant Calculate the total time talcen to travel blom Themes of the most of the engine of the train and the train retards uniformly. During the First 305, the covers to the train comes to rest after the next 30s Calculate the: Istial speed of the train Total distance the train moves before coming to rest Tuo cars are in a race Car A starts for resten forma acceleration of 0.6s. Ca B also stars forests later for the same and follows ze same path with uniform acceleration of as Hose cars have gone when ca Bovertakes car A 06 ) Ssceret og 60 slows down a 153 How long does it take to travel 70m as it stops. Te does all standing scance of 135 apart towards each at 6.75mis and 525mis spectively. Then they mean bor see they for the point where the slower dag was standing? Projesile mine Asso very sad a speed of Ols. Calculate The guest bezgan reached Tietze to reach the ground Is velocity afers Besoeverically and recen to the ground 4 seconds later. Determine the a parceleropped ca 16 deep site Find the e to reach the bottom of the start velocity of the parcela de botom of the shaft 08 bis Ered a 300s Focage positioned at 30° to the ground Calculatet Horizontal and the vertical components of the velocity The horizontal displacement of the shell The main beaght the shell reaches Thoratles are placed on top of high table. The first marble is kicked off the table at a speed of 3. The second marble drops of the table vertically down. How Ez apart do the marbles and on the ground? 5) What is the difference in time taken to reach the ground? ON project te is fired with low velocity towards a 10m tall building at an angle of 40° The grou levei Estance between the firing point of the projectile and the bottom of the building is 60m. If the project is the top edge of be builtag calculate the
