  1. CLASS-IX SAM INSTITUTE AZAD CHOWK RUSTAMPUR PHYSICS WORKSHEET QI ) Consider the situation shown in figure. -3 -2 1 2 3 metres a) What is the position of a particle when it is at PI, and when it is at P2? b) Are the two positions the same? c) Are the two distances of the particle from the origin the same? Q2) The position of a particle going along a straight line is x = 50 m at 10:30 a.m. and x = 55 m at 10:35 a.m. Find the displacement between 10:30 a.m. and 10:35 a.m. Q3) A car covers 30 km at a uniform speed of 60 km/h and the next 30 km at a uniform speed of 40 km/h. Find the total time taken. Q4) Convert 15 m/s into km/h. Q5) The average speeds of a bicycle, an athlete and a car are 18 km/h 7 m/s and 2 km/min respectively. Which of the three is the fastest and which is the slowest? Q6) The velocity of a car at 10:50 a.m. is 60 km/h and at 10:52 a.m. it is 80 km/h. Find acceleration in the given period. Q7) An object is sliding down an inclined plane. The velocity changes at a constant rate from 10 cm/s to 15 cm/s in two seconds. What is its acceleration? Q8) A particle moves through a distance of 3 m due east and then 4 m due north. (a) How much is the net distance traversed (b) What is the displacement in whole journey?
