In the 1992 summer olympics the german four man kayak team covered 1 km in just under 3 minutes. suppose that between the starting point and the 150 m mark the kayak steadily increases its sped from 0.0 m/s to 6.0 m/s so that it’s average speed is 3.0 m/s

Complete Question:

In the 1992 Summer Olympics, the German four-man kayak team covered 1 km in just under 3 minutes. Suppose that between the starting point and the 150 m mark the kayak steadily increases its speed from 0.0m/s to 6.0 m/s, so that its average speed is 3.0 m/s.

part a- how long does it take to cover the 150 m?

part b- What is the magnitude of the average acceleration during that part of the course?

a. To cover the 150 m mark, it takes 50 s.

b. The magnitude of average acceleration during 0 to 150 m part is 0.12 m/s².

Explanation:

a. Time taken to cover the first 150 m = t = ?

Average speed = v = 3 m/s

Distance = S = 150 m

We know that;

v = S/t

Rearranging this equation, we get:

t = S/v

t = 150/3

t = 50 s

b. average acceleration till 150 m = a = ?

We know that acceleration is given by rate of difference of initial and final velocity:

a = (final velocity - initial velocity)/t

a = (6 - 0)/50

a = 0.12 m/s²

answer: i don't know the answer good luck
