Select the correct answer. Lisa’s doctor tells her that she needs to eat more foods that contain calcium to maintain her bone he

Harlamova29_29 [7]

The answer is B, if your body doesn’t consume enough vitamin D, it takes calcium from your bones. This is called losing bone mass. Losing bone mass makes the inside of your bones weaker and have a higher risk of fractures (especially children).

A 1.2 kg ball moving due east at 40 m/s strikes a stationary 6.0 kg object. The 1.2 kg ball rebounds to the west at 25 m/s. What

RSB [31]

V_2' = v_1 + v_1'
So v_2' = 40 + -25
We have set east to be + and west -
Which gives us 15 m/s. So thats how fast the 6 kg object is going.
This is true for an elastic collision.

A truck moves 60 kilometers east from point A to point B. At point B, it turns back west and stops 15 kilometers away from point

iogann1982 [59]

Answer:

Distance: 75 km

Displacement: 45 km

Explanation:

- Distance is a scalar quantity that refers to the total space covered by an object. It is calculated as the sum of the distances covered in each motion, regardless of their direction. therefore in this case:

distance = 60 km + 15 km = 75 km

- Displacement is a vector quantity whose magnitude is equal to the difference between the final point and the starting point of the motion, so it also takes into account the direction of each motion. In this case, the truck moves 60 km east, and then 15 km west: if we call '0' the starting point, the final point will be then

$p_B = 60 km - 15 km=45 km$

And so the displacement is

$d=p_B - p_A=45 km - 0 = 45 km$
