V(t)=t^2+2 (m/s) for t=0, x(0)=4m find the acceleration and the kinematic equation

Acceleration can be found by differentiating v(t) by t:

dv/dt =d(t^2+2)/dt

=d(t^2)/dt + d(2)/dt

=2tdt/dt + 0

=2t

The displacement x(t) can be found by integrating v(t) by t

x(t) = int(t^2 + 2)dt

= t^3/3 + 2t + c

When t=0, x(0)=4=0+0+c

So c=4

x(t) = t^3/3 + 2t + 4

v(t) = t^2 + 2

a(t) = 2t

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
