Answer:
minimum distance will be 13.33 m
Explanation:
We have given the speed of both the car = 80 km/h
We know that 1 km =1000 m
And 1 hour = 60×60 =3600 sec
So
Reaction time is given as t = 0.60 sec
Minimum distance will be equal to the distance driver needed during reaction time
So minimum distance = u ×t =22.22 ×0.60=13.33 m
Moon and Earth have different gravitational constants- g. g on the Earth is <span>equal to 9.8 m/s^2 while g on the moon is equal to 1.6m/s^2.
</span><span>Let assume that two balls are thrown: one on Earth and one on Moon and that their kinetic energy is the same.
The kinetic energy is E=(m*v^2)/2.
So, this means that t</span><span>he ball would fall much more slowly on Moon than on Earth. Every aspect of the ball's fall would be slower.

Answer:
the total travled is 2.75
Explanation:
because if you divide 110 by 40 you get 2.75
Answer:
5.25MJ
Explanation:
Considering the weight of the skydiver constant over the descent -ie, the acceleration of gravity not decreasing as you go up the earth surfice, the work is simply the product of the two:
