MOTION EXAMPLES TEST – l Total marks: 30 Time allotted: 1 hour ___________________________________________________________________________________

All questions carry equal marks Q-1)A Sprinter Runs 200m in 2s. Calculate his average speed in m/s and km/h. Q-2)Gaurav on his moped travels 5 km at 20 km/h and next 5 km at 30 km/h. Calculate his average speed. Q-3)Initial and final odometer readings taken by Mohan during his journey are 1048 km and 1096 km. If he takes 40 min., calculate average speed. Q-4)On applying brakes, speed of the jeep reduces to 18 km/h from 72 km/h in 10 s. Calculate the retardation. Q-5)A scooterist, moving on straight highway at 54 km/h sights an obstacle at a distance of 50 m and applies brakes to produce -2.5 m/s2 retardation. Will he be able to avoid the accident? Q-6)A cyclist is moving on a circular path of 63 m radius. If he takes 132 s to complete the round, calculate the linear speed of the cycle. Q-7)When brakes are applied to a car running on a straight road retardation of -4 m/s2 is produced. It stops after 3 s. Calculate the distance traveled after brakes are applied. Q-8) A motor car travels first 30 km of its journey on a highway at 60 km/ h and next 30 km at 90 km/h at uniform speed. Calculate the average speed. Q-9) Convert 90 km/h to m/s Q-10) Convert 3600 m /s to km / h.
