Evaluate:
HORIZONTAL MOTION
1. The motion of a particle along the x -axis is described by the equation
m v = (3 s2) t + (0.5 m) t2 s2
where x is in meters, and t is in seconds. Determine the following:
a. Position of the particle 3 seconds after starting
b. Displacement from 2 sec to 5 sec c. Average velocity during first 5 seconds d. Velocity at t = 4secs
UARM:
e. Average acceleration during the second 3 seconds
f. Acceleration at t = 5 secs g. Time the particle moves at 20m/s
h. The acceleration and velocity at start of motion 1. A car is moving at uniform acceleration. Its velocity
a. Position of the particle 3 seconds after starting
b. Displacement from 2 sec to 5 sec
c. Average velocity during first 5 seconds
d. Velocity at t = 4sec
