It’s C
Cause Impulse is found by multiplying the force and change in time (which is simply time)
So if you rearrange the equation for time you end up dividing Impulse by force.

A football punter accelerates a football from rest to a speed of 15 m/s during the time in which his toe is in contact with the

ioda

Answer:

Force, F = 44 N

Explanation:

Given that,

Initial speed of the football, u = 0

Final speed, v = 15 m/s

The time of contact of the ball, t = 0.15 s

The mass of football, m = 0.44 kg

We need to find the average force exerted on the ball. It is given by the formula as :

$F=ma\\\\F=\dfrac{mv}{t}\\\\F=\dfrac{0.44\times 15}{0.15}\\\\F=44\ N$

So, the average force exerted on the ball is 44 N. Hence, this is the required solution.

Narrow belts of high-speed winds that blow in the upper troposphere and lower stratosphere are known as

Drupady [299]

<h2>Jet Stream</h2>

Explanation:

Jet streams are the winds that flow in the upper levels of the atmosphere.
These are relatively narrow bands of strong wind.
These high-speed winds blow from west to east in jet streams.
Sometimes, the flow of wind shifts from north to south.
Jet streams follow the boundaries between hot and cold air.
