Question

A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 ms^-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

$\huge\bold\purple{Answer:-}$

⏩ Here, u= 0, a= 3 ms^-2, t= 8s

We know that, s= ut + 1/2 at²

= 0 × 8 + 1/2 × 3 × (8)²

= 96 m. Ans.
