Question

a motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 m s-2 for 8.0s .how far does the boat travel during this time ​

Answer 1

equation of kinematics: motion :

        s = u t + 1/2 a t²

  here u = 0 m/sec  a = 3.0 m/sec/sec    t = 8.0 sec

          s  = 0 * 8.0 + 1/2 * 3 m/sec² * (8.0 sec)²

     distance travelled in 8 sec = 96 meters

Answer 2
