During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a vel

zmey [24]

Answer:

Mass of receiver is 92 kg

Explanation:

We have given mass of tackler $m_1=100kg$

Let the mass of receiver is $m_2kg$

When tackler moving alone velocity is $v_i=4.8$ m/sec

And when tackler and receiver is together velocity is $v_f$ = 2.5 m/sec

So from conservation of momentum

$m_1v_i=(m_1+m_2)v_f$

$100\times 4.8=(100+m_2)\times 2.5$

$2.5m_2+250=480$

$2.5m_2=230$

$m_2=92kg$

So mass of receiver is 92 kg

Which term means the weight of air measured in units of force per area?

Norma-Jean [14]

Force per area is pressure so I think the answer would be air pressure. Relative pressure sounds like it is a measure of pressure relative to something else.
