Physics problem with calculs

[From: ] [author: ] [Date: 11-09-27] [Hit: ]
If so, what would be going on? If not,No.acceleration is derivative of v. the directions of both vectors have to be same.......
1.A honeybee's position as a function of time is given by x =
10t-t^3, where t is in seconds and x in meters. What is its velocity
at t = 3.0 s

3. Is it possible for a helicopter to have an acceleration due east
and a velocity due west? If so, what would be going on? If not, why
not

[1]
x = 10t - t³
velocity v = dx/dt = 10 - 3t²

v (at t=3) = 10 - 3(3)² = -17


[3]
No.
a = dv/dt
acceleration is derivative of v. the directions of both vectors have to be same.
