DochEvi [55]

Based on the given details with this question, I can say that the direction of motion is not conserved. This is because the boat is subjected to an external force because of water resistance. So, the answer for this question would be NO.

A truck covers 40.0 m in 7.45 s while uniformly slowing down to a final velocity of 3.50 m/s.

astra-53 [7]

Answer:

(A) Original velocity will be 7.244 m /sec

(B) Acceleration will be $-0.5026m/sec^2$

Explanation:

We have given distance covers by truck s = 40 m

Time taken by truck to cover this distance t = 7.45 sec

Final velocity v = 3.50 sec

According to second equation of motion

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

$40=u\times 7.45+\frac{1}{2}\times a\times 7.45^2$

$7.45u+27.751a=40$ -----eqn 1

According to first equation of motion

v = u + at

So $3.5=u+7.45a$ -----eqn2

Solving equation 1 and 2

a = $-0.5026m/sec^2$

And u = 7.244 m /sec

(A) Original velocity will be 7.244 m /sec

(B) Acceleration will be

$-0.5026m/sec^2$
