السلام عليكم
ارجو المساعده:confused::confused:
السؤال الأول
The position of a particle moving along the x axis is given by x = 6.0t2 – 1.0t3, where x is in
meters and t in seconds. What is the position of the particle when it achieves its
maximum speed in the positive x direction?
السؤال الثاني
The velocity of a particle moving along the x axis is given for t > 0 by vx = (32.0t –
2.00t3) m/s, where t is in s. What is the acceleration of the particle when (after t = 0) it
achieves its maximum displacement in the positive x direction?
.
السؤال الثالث
The position of a particle as it moves along the x axis is given for t > 0 by x = (t3 – 3t2 +
6t)m, where t is in s. Where is the particle when it achieves its minimum speed (after
t = 0)?
السؤال الرابع
The position of a particle moving along the x axis is given by x = 4.0te–t, where x is in m
and t is in s. What is the position of the particle when its acceleration is zero?
.
