Question

A motor boat starting from rest on a lake accelerates in a straight line at a constantrate of 3.0m/s2 for8.0s.How far does the boat travel during this time?​

Answer 1

Answer:

Hello, Good Evening

Step-by-step explanation:

Given,

Initial Velocity (u) = 0

Final Velocity (v) = x

Acceleration (a) = 3 m/s^2

Time (t) = 8s.

Using the First Equation of Motion, v = u + at, we get,

x = 0 + 3(8)

x = 0 + 24

x = 24 m/s.

Therefore, the Motor Boat will be at 24 m/s after 8 seconds....

HOPE THIS HELPS....

Wishing you a very Happy Raksha Bandhan......

Answer 2

Step-by-step explanation:

GIVEN:

Vo = 0 m/s

a = 3.0 m/s²

t = 8.0 s

REQUIRED:

d = ?

SOLUTION:

d = 1/2 at²

d = 1/2 (3.0 m/s²)(8.0 s)²

d = 96 m ANSWER
