Suppose that the position vector for a particle is given as a function of time by vector r(t) = x(t)i hat bold + y(t)j hat bold, with x(t) = at + b and y(t) = ct2 + d, where a = 2.00 m/s, b = 1.30 m, c = 0.134 m/s2, and d = 1.04 m.

(a) Calculate the average velocity during the time interval from t = 2.10 s to t = 4.15 s.
vector v = m/s
(b) Determine the velocity at t = 2.10 s.
vector v =
m/s
Determine the speed at t = 2.10 s.

answer: hey stupid

what the hell you doing i need you at my house

explanation: it's me king omoregie

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
