<span>assuming the pitch is 100yards long, the player runs 100yards to the other goal then a further 50 yards back to the 50-yard line. So he/she runs 150yards in 18s
150/18 = 8.33yards per second average speed.
Initial velocity = 0, average velocity =8.33
Vav = (Vinitial+Vfinal)/2
Vav = 4.16m/s</span>
Answer with Explanation:
We are given that
Distance,r=0.27 m
Tangential speed=v=0.49 m/s
a.Angular speed ,
Using the formula



Time period,
b.Amplitude,A=Distance of small eraser from the center of a turnable =0.27 m
c.Maximum speed,
d.Maximum acceleration=
Answer:
7 hours
Explanation:
The total charge contained in the battery is

And this is a charge, since it is a current multiplied by a time:

The current drawn by each headlight (which is the charge consumed per second) is

Since we have two headlight, the total current drawn is

Therefore, the total charge consumed by the two headlights each hour is

So, the time before the battery is dead is
