Question

A motorist starting from rest on a lake accelerate in a straight line at a constant rate of 3mper second square for 8secobds how Dar does the boat travel during thus 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
