Question

11. What force is required to accelerate 2000 kg, car from 5 m/sto 25 m/s in a
time of 10seconds​

Answer 1

Answer:

4000 newton is answer

Explanation:

acceleration =v-u/t

Answer 2

Answer:-
The force would come out to be 4000 N .

Explanation:

Given :-
mass of the car = $2000$kg
Total distance travelled = final distance - initial distance
                                        =   $25$ m/sec - $5$ m/sec
                                         = $20$ m/sec
Time = $10$ seconds

To find :- Force

     We know that ,
           force = mass × acceleration
Acceleration = Total distance travelled / Total time taken
                     =  $20 / 10$
                      = $2$ m/$sec^{2}$

Now,
        Force = mass × acceleration
                   = $2000$ × $2$
                   = $4000$ kg.
Therefore the force would be , $4000$ N.
