Question

A car covers the first 200 m in 30 seconds and the next 400 m in 30 seconds. Its average speed is ___ m/s.

hintHint:

10 m/s

The correct answer is: 10


    Average speed = total distance covered / total time taken
    = (200 + 400)/ (30 + 30)
    = 600/60
    = 10 m/s

    Peter wants to modify the formula for acceleration
    i.e., a = (v – u)/ t
    Where v = final velocity, u = initial velocity, t= time, a = acceleration, to suit the special case of freefall of a ball dropped from the top of a building. He chooses to make the following substitutions in the formula.
    a. v= 0
    b. u= 0
    c. a= 9.8 m/s2
    Identify the correct substitutions.
