Question

2.) if the
velocity
a body depends upon time i.e
v = 5t²+3t+2 then find the total distance travelled by
body
from
time = 0 to 5 seconds
​

Answer 1

Answer:

Here v = dx/dt .

=) v = 5t^2+3t+2

now use integration of dx from 0 to 5

 5

∫ dx

0

s-0 = 5*25 + 3*5 +2

s = 125 +15 +2

s = 142 m

Once pls cross check . The method correct , but answer is doubtful . Use this metthod to find out your answer :)
