An object starts at rest. its acceleration over 30 seconds is shown in the graph below:

in the graph above, what is the instantaneous speed of the object after the first five seconds?

The instantaneous speed of the object after the first five seconds is 12.5 m/s.

(C) is correct option.

Explanation:

Given that,

An object starts at rest. Its acceleration over 30 seconds.

We need to calculate the instantaneous speed of the object after the first five seconds

We know that,

Area under the acceleration -time graph gives speed.

According to figure,

Hence, The instantaneous speed of the object after the first five seconds is 12.5 m/s.

that would be b i just took the test : )

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
