A rectangular field is 150 m x 60 m. Cyclists Joe and Jim start together cycling at speeds 21m/min and 28 m/min respectively. They cycle along the track around the field at the same moment. After how many minutes do they meet again at the starting point?

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. After how many minutes will they meet again at the start- ing point?

  • Two bodies begin to move from rest in the same straight line at the same instant of time from the same point. The first moves with constant velocity of 40 ms and the second starts with uniform acceleration of 4 ms. The time which the distance between them is maximum is :

    A
    20 s
    B
    10 s
    C
    40 s
    D
    5 s

  • A body is at rest at x = 0. At t = 0, it starts moving in the positive x-direction with a constant acceleration. At the same instant another body passes through x = 0 moving in the positive x-direction with a constant speed. The position of the first body is given by X_(1) (r) after time t and that of the second body by x_(2) (r) after the same time interval. Which of the following graphs correctly describes ( x_(1) - x_(2) ) as a function of time t?

    A
    B
    C
    D

  • Two bodies begin a free fall from the same height at a time interval of Ns. If vertical separation between the two bodies is 1 after second from the start of the first body, then is equal to :

    A
    `sqrt(nN)`
    B
    `(1)/(gN)`
    C
    `(1)/(gN)+(N)/(2)`
    D
    `(1)/(gN)-(N)/(4)`

    From a station two trains start at the same time. One train moves west and the other moves north. First train moves 5 km/hr faster than the second train. If, after 2 hours, the distance between the two trains is 50 km, find the average speed of each train.

    The conversion of molecules X to Y follows second order kinetics. IF concentration of X is increased to three times how will it affect the rate of formation of Y.

    A car starts from a point P at time t = 0 seconds and stops at point Q. The distance x, in metres, covered by it, in t seconds is given by x = t^(2)(2-t/3) . Find the time taken by it to reach Q and also find the distance between P and Q.

    In a potato race, a bucket is placed at the starting point, which is 5m from the first potato, and the other potatoes are placed 3m apart in a straight line. There are ten potatoes in the line (fig.). A competitor starts from the bucket, picks up the nearest potato, runs back with it, drops it in the bucket, runs back to pick up the nest potato, runs to the bucket to drop it in, and she continues in the same way until all the potatoes are in the bucket. What is the total distance the competitor has to run ? [Hint : To pick up the first potato and the second potato, the total distance (in metres) run by a competitor is 2 xx 5 + 2 xx (5 + 3) ]
