Motion in straight line practice problems
Question 1 Distinguish between average acceleration and instantaneous acceleration. (2)
Question 2 Can a body have constant speed and still have a varying velocity. (1)
Question 3 Is it possible for a body to be accelerated without speeding up or slowing down. If so give an example (1)
Question 4 A man standing on the edge of a cliff throws a ball straight up with a speed of 8 Km/h and then throws a ball down with a speed of 8 Km/h from the same position. What is the ratio of speeds with which the ball hit the ground.
Question 5 When an observer is standing on earth, the tree and houses appear stationary to him. However, when he is sitting in a moving train, all these objects appear to move in backward direction. Why?
Question 6 Derive the following equations of motion for an object moving in constant acceleration along a straight line.
[ If you get extra time try to derive above equations using Integration method]
Question 7 The acceleration experienced by a boat after the engine is cut off , is given by
where is a constant. If is the magnitude of velocity at the cut off , find the magnitude of the velocity at time after the cut off.
Question 8 The relation between and distance is where and are constants. Express the instantaneous acceleration in terms of instantaneous velocity.
Question 9 If in case of a motion , displacement is directly proportional to the square of the time elapsed, what do you think about its acceleration. Would it be constant or variable. Justify your answer.
Question 10 A body covers one-third of its journey with speed , next one third with a speed and last one third with a speed . Calculate the average speed of the body during the entire journey.
