    Question

    What will be the initial velocity of a car which covers

    a distance of 200 km in 5 hours, having an acceleration of 4 km/hr and final velocity as 50 km/hr.
    A 20 Correct Answer Incorrect Answer
    B 30 Correct Answer Incorrect Answer
    C 40 Correct Answer Incorrect Answer
    D 50 Correct Answer Incorrect Answer

    Solution

    We know V= U + at where V is the final velocity, U is the initial velocity, a is the acceleration and t is the time. Hence, putting V= 50, t=5, a=4 we get u as 30 km/hr. Hence, initial velocity is 30 km/hr Hence, option A is correct.
