The whale shark is the largest of all fish and can have the mass of three adult

ch4aika [34]

Answer:

m = 20,000 kg

Explanation:

Force, $F=2.5\times 10^4\ N$

Acceleration of the shark, $a=1.25\ m/s^2$

It is required to find the mass of the shark. Let m is the mass. Using second law of motion to find it as follows :

F = ma

Putting the value of F and a to find m

$m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20,000\ kg$

So, the shark's mass is 20,000 kg.

A car traveling at 15 m/s starts to decelerate steadily. It comes to a complete stop in 5 seconds. What is its acceleration ?

Nataliya [291]

Answer:

$-3m {s}^{-2}$

Explanation:

The initial velocity, u, of the car=15m/s

The final velocity, v, of the car =0m/s

Time, t, taken for the car to come to a stop=5s

Acceleration is calculated by,

$a= \frac{v - u}{t}$

By substitution,

$a= \frac{0- 15}{5}$

$a= \frac{- 15}{5}$

$a = -3 {ms}^{ - 2}$

The negative sign implies that the car has decelerated.
