A body moves along a linear path and its rate of change of velocity varies with time and is written as a=2-3t, where t is the time in second. After 5 second, from start of observation its velocity is determined to be 20 m/s. After 10 second from start of observation, the body is at 85 m far from the origin. Determine the following:a. Rate of change of velocity and velocity at the start of motion. b. Distance from the origin at the start of observation c. Time after start of observation in which the velocity becomes zero

A body moves along a linear path and its rate of change of velocity varies with time and
is written as a=2-3t, where t is the time in second. After 5 second, from start of observation
its velocity is determined to be 20 m/s. After 10 second from start of observation, the body
is at 85 m far from the origin. Determine the following:a. Rate of change of velocity and velocity at the start of motion.
b. Distance from the origin at the start of observation
c. Time after start of observation in which the velocity becomes zero.
