Answer:

Learning the formula.multiply mass accelebrations.the force(F)required to move an object of mass(M) with an acceleration (a) is given by the formula F = m x a.so, force = mass multiplied by accelebration.

You often hear people, particularly TV announcers, talk about a "high rate of speed." What do you think they mean? According to
NikAS [45]

TV announcer intend to mean "chnage of speed or velocity" by "High rate of speed" and in Physics domain it would mean "acceleration"

Explanation:

It is common to observe TV announcer saying certain events were occurring “with a high rate of speed”. By saying this they intend to mean that the event was rapid in its occurrence. It can also mean that the change in speed of the happening was very rapid/fast.

However, the same terms connote altogether a different expression in Physics domains. Speed is a scalar quantity with no direction. Hence most of the times speed mean velocity when the direction is also provided. “high rate of speed” would mean a change of velocity per unit time which is acceleration. Hence in Physics domain, the term would stand for acceleration.

It is the final seconds of an ice hockey game between the Flyers and the Bruins. The Bruins are down by 1 point. With 20 s left
liberstina [14]

Answer:

a

P =0.1094 \ m past the goal post

Yes the Flyers won the match

Explanation:

Generally the distance covered by the pluck during the last 1.25 seconds is mathematically represented as

     D =  ut + \frac{1}{2} * a * t^2

=>  D =30  * 1.25 + \frac{1}{2} * (-0.5) * (1.25)^2

=>   D =37.1094 \ m

Generally the position of the puck when the game clock reaches zero is mathematically represented as

     P = 37.1094 -37

       P =0.1094 \ m past the goal post

Given that the Bruins where one point down and Flyers scored another goal  it means that the flyer are now two point up hence they won the match
