Question

A car starts from rest and attains a velocity of 50 km per hour in 5 minutes if acceleration is uniform find the acceleration and distance travelled by the 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       
        a  = (250/18 - 0)/300       
        a  = (250/18)/300       
         a = 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.
