Answer 1

Answer:

1. A,B,C

2.

A. Increase

B. 2 m/s /s

3.

A. -0.5 m/s /s

B. Gravity will cause the acceleration to be positive. So speed will increase with time.

Explanation:

1. A _ because, speeding car. ( car is speeding up(or down. does not matter, it os changing)).

B _ because applying break will slow down the moto.

C _ because velocity os vector. It has direction. If somehow direction changes, it will be counted as a change in velocity.

2. V was 0, now it is 10 ( increased)

So, change is 10-0 = 10

It took 5 second to make a difference of 10 meter per second.

5 second caused 10 m/s difference

so, 1 sec will cause 10m/s ÷ 5 sec = 2m/s /s = 2ms^-2

3. V was 2 and now is 0.5 (decreased)

changed = 0.5 - 2 = -1.5

[ in case of change, always take away past from present ]

3 second made a difference of -1.5

so, 1 second will make (-1.5) ÷ 3 ms^-2 = -0.5 ms^-2.
