Answer:

The equation says that due to variation in temperature is

delt T = .59 m/s / C = 16 C * .59 m/s = 9.44 m/s

So v = 332 m/s + 9.44 m/s = 341 m/s (to three significant figures)

Sever21 [200]

Answer:

$a = 12.32 \ m/s^2$

$F = 1017.52 \ N$

Explanation:

From the question we are told that

The length of the Chinook salmon is $l = 1.50 \ m$

The mass of the Chinook salmon is $m = 46.0 \ kg$

The upward velocity in water is $u = 3.00 \ m/s$

The upward velocity in air is $v = 5.80 \ m/s$

Generally from kinematic equations

$v^2 = u^2 + 2as$

=> $5.80^2 = 3.00^2 + 2 * a * [ [\frac{2}{3} * l ]$

=> $5.80^2 = 3.00^2 + 2 * a * [ [\frac{2}{3} * 1.5 ]$

=> $5.80^2 = 3.00^2 + 2 * a * [1 ]$

=> $a = 12.32 \ m/s^2$

Generally magnitude of the force F during this interval in N is mathematically represented as

$F = m (a + g )$

=> $F = 46.0 (12.32 + 9.8 )$

=> $F = 1017.52 \ N$

Acceleration involves a change in __________.

uysha [10]

"Acceleration" is any change in speed or direction of motion ...
slowing down, speeding up, or curving away from a straight line.

You and I, and all other students of Physics, must re-educate
people. We have to tell everyone that 'acceleration' does NOT
mean 'speeding up'. AND, it doesn't even necessarily mean
any change in speed.
