Question

How far does the
30 kmh. What is I U
1. A motorboat starting from rest on a lake accelerates in a
line at a constant rate of 3.0 ms for 8.0 s. How far
boat travel during this time​

Answer 1

Answer :

Given ,

initial velocity = 0

Acceleration = 3.0m/s

Time = 8.0s

Now,

V = u + at

= 0 + 3.0 × 8.0

= 0 + 24

= 24m

$s \: = ut + \frac{1}{2} {at}^{2}$

$\: \: = > 0 \times 8 + \frac{1}{2} \times 3.0 \times {8}^{2} \\ = > \frac{1}{2} \times 3.0 \times 64 \\ = > 3 \times 32 \\ = > 96m$

Hence, The boat travels 96m during this time.
