2.An object is thrown up into the air with an initial velocity of an initial velocity of 40m/s. Neglect air friction. How long does it take to reach the high point?

How high does it rise?

Where is the object and how fast is it moving 8.16 seconds after it was released?

3. A car starts moving from rest along a straight line and accelerates uniformly at a rate of 2m/sq for 5 seconds.

What is the final velocity reached after 5 seconds?

How far did it move during this time?

With the same acceleration (2m/sq), how long will it take to move 60 meters beyond the starting point?

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
