an object moves along a straight path at a speed v(t)=4t^2+3t+2 in m/s, where t=time in seconds. find the distance travelled after 4 seconds?

welshfella · Answer

you need to find the distance so you have to integrate

anonymous · Answer

the choices are:
a) 112.56 m 
b) 135.68 m
c) 117.33 m
d) 125.75 m

anonymous · Answer

i already derive this v(t)=4t^2+3t+2 and plug in t=4

anonymous · Answer

u have o integrate it

anonymous · Answer

nd hten plug in t=4

welshfella · Answer

can you integrate the expression

anonymous · Answer

ok wait

anonymous · Answer
