We timed how long it took for the ball to travel 1 meter several times, so we could calculate an “average” time to use in the ve

damaskus [11]

We need to find the average speed of the ball during the motion of 1 m

In order to find that we took several reading and found following times to cover the distance of 1 m

t1 = 2.26 s

t2 = 2.38 s

t3 = 3.02 s

t4 = 2.26 s

t5 = 2.31 s

Now in order to find the average time we can write

$T_{mean} = \frac{t_1 + t_2 + t_3 + t_4 + t_5}{5}$

$T_{mean} = \frac{2.26 + 2.38 + 3.02 + 2.26 + 2.31}{5}$

$T_{mean} = 2.45 s$

So average time to cover the distance of 1 m by ball will be 2.45 s

here 3.02 s is not the average time but we can say it is the median of the readings of all possible values which we can not use in our calculation as average time

Suppose you are watching an ice-hockey game with some classmates. As the puck is sliding across the ice at a relatively constant

zavuch27 [327]

Answer:

the answer, the correct one is C

Explanation:

Let's propose the solution of this problem to know which explanation is correct, when the concha stick with the disc is an impulse exercise

I = ΔP

∫ F dt = pf-po

∫ F dt = m v_f - m v₀

Therefore, during the time that the contact lasts, a force is applied to the disk, which causes that if the amount of movement increases and therefore its speed increases, when the constant ceases the forces are reduced to zero and the disk no longer changes its momentum following with constant velocity.

When reviewing the answer, the correct one is C
