Q.1

Answer . Momentum = mass x velocity

Momentum/mass = velocity

5/0.8 = velocity

6.25 m/s = velocity

Q.2

Answer . F = ma => a = f/m => a = 7/3.2 => a = 2.1875m/s²

A mover does 422 J of work pushing a crate 8.39 m. How much force did he exert?

kicyunya [14]

Answer:

50.3N

Explanation:

Work done = force x distance

422J. = force x 8.39m

÷8.39 both side to get force

Force is 50.3N to 1 d.p.

Check:

50.3 x 8.39=422.017J

Same as 422J to 1 d.p

Describe how you could use two photographs taken at a different time to prove that the moon is in motion

Slav-nsk [51]

You can prove that moon is in motion by taking two photos with the following features:

They are taken at the same hour and minute.
They are taken on two different nights.
They are taken from the same location.

This would allow an accurate comparison and would should the moon's motion.

I hope this helped! :)

At summer camp, the swimming course runs the length (L) of a small lake. To determine the length of the course, the camp counsel

Oduvanchick [21]

Answer:

The length of the swimming course is 47.16 meters.

Explanation:

It is given that the right triangle overlaps the lake and hypotenuse L runs through the length of the lake. Thus length of the lake will be the length of this hypotenuse.

The instructors have conducted measurements of the right triangle and has found the legs to be 25 and 40 meters. The sum of squares of base and height of a right triangle gives the value of its hypotenuse according to Pythagoras theorem.

Thus $h^2+b^2=H^2$

b - base

h - height.

$40^2+25^2=1600+625=2225$

$H=\sqrt{2225}=47.16 m$
