Question

Please provide step by stepinstructions thanks.

The vector position of a particle varies in time according tothe expression r = 7.20 i - 8.80t^2 j where r is in meters and t isin seconds.
(a) Find an expression for the velocity of the particle as afunction of time. (Use any variable or symbol stated above asnecessary.)
v =________ m/s

(b) Determine the acceleration of the particle as a function oftime. (Use any variable or symbol stated above as necessary.)
a =________ m/s^2

(c) Calculate the particle's position and velocity at t = 5.00s.
r = ________ m
v =_________ m/s
