Q1) The position of a particle traveling along a straight line is s(t) = (t3-3t2+C) ft, where t is in seconds and C is a constant. If s = 4 ft when t= 0, determine the velocity of the particle when t 4 s. What is the total distance traveled during the time interval t 0 to t = 4 s? Also, what is the acceleration when t 2 s? %3D

Q1) The position of a particle traveling along a straight line is s(t) = (t3-3t2+C) ft, where
t is in seconds and C is a constant. If s = 4 ft when t = 0, determine the velocity of the
particle whent = 4 s. What is the total distance traveled during the time interval t = 0
to t = 4 s? Also, what is the acceleration when t = 2 s?
Q2) The weigh w1 is connected by belt over pully if there is no friction and the weight
w2 = 300 N. if the block w2 move downward with the incline at a constant speed,
what is the weight of the other block (w1).
W2
0 = 37°
