A particle moving along a straight line is subjected to a deceleration a=(-2v3) m/s2, where v is in m/s. If it has a velocity v=8m/s and a position s=10m whent=0, determine its velocity and position when t=4s.
the velocity of a particle traveling in a straight line is given by v=(6t-3t^2)m/s, where t is in seconds, if s=0 when t= 0. determine the particles deceleration and position when t=3s. how far has the particle traveled during the 3s time interval and what is its average speed?

Suppose that, at time t = 0, a particle with mass 3 has position vector ⃗r(0) = 4⃗j − ⃗k and velocity ⃗v(0) = −5⃗j − 13⃗k. The particle is then subjected to a constant force of F⃗ = 9⃗ı + 6⃗k. (a) Find the position of the particle (as a function of time). (b) When is the particle moving most slowly? Compare the minimum speed with the speed at times t = 1 and t = 4. Thank you!...
