I have attached my question in picture pls solve it I will mark u brainliest​

Answer 1

Answer:

l think it's option c.3.75m/s but not sure

Answer 2

Explanation:

as we know,

$s = v \times t$

s=distance

v=velocity

t=time

at t=10 sec

$s = v \times t$

$s = 10 \times 5$

$s = 50 \: m$

at time=15. t=15-10=5 sec

$s = v \times t$

$s = 5 \times 2$

$s = 10 \: m$

at time=25. t=25-15=10 sec

$s = v \times t$

$s = 10 \times 2$

$s = 20 \: m$

as we know,

$average \: velocity = total \: distance \div total \: time$

$average \: velocity = (50 + 10 + 20) \div (10 + 5 + 10)$

$average \: velocity = 80 \div 25$

$average \: velocity = 3.2 \: m {s}^{ - 1}$

so, the average velocity of the body during the time interval (0-30)sec is 3.2 m/s^2
