Comment if you want me to give you the step by step thank you
we know that
acceleration due to gravity is 9.8m/s^2
so, we get
and acceleration will always be constant
we know that
integral of acceleration is velocity
so, we can integrate both sides
we are given
v(0)=35m/s
we can use it and find C
now, we can plug it back
we know that
integral of velocity is height
we can integrate it again
now, we have
s(0)=6
we can use it and find C
now, we can plug back C
and we get
