Question

A car starts from rest and attains a velocity of 50 kilometre per hour in 5 minutes if acceleration is uniform find acceleration and distance by car

Answer 1

Hi.

Here is your answer-----

Given-----
Initial speed(u) = 0
Final speed(v) = 50 km/hr.
                        = 50 x (5/18) m/s
                       = 250/18 m/s
Time(t) = 5 minutes
            = 5 x 60 seconds
            = 300 seconds
First,
Using formula for acceleration,
     a = (v -u)/t
        = (250/18 - 0)/300
        = (250/18)/300
        = 5/108 m/s^-2

Now,
Using formula,
         Final Speed = Distance/Time
                250/18  = Distance/300
             Distance = 12500/3 m

Hope this will help u.

Have a nice day.
