1. The coordinates of a particle moving in the yz-plane are given as a function of time by y = 5m –
(2m.s -1 )t and z = (2ms -2 )t 2 .
a. What is the average velocity for the first 3 seconds.
b. Calculate the velocity and acceleration vectors of the particles as a function of time.
c. Calculate the magnitude and direction of the particle’s velocity and acceleration at t=2 sec.
