# An object is at rest at #(1 ,7 ,2 )# and constantly accelerates at a rate of #1 m/s^2# as it moves to point B. If point B is at #(3 ,7 ,4 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.

The answer is

so,

We employ the formula

- How do you calculate the "change in speed"?
- Can you help me interpret the motion of the following position-time graph?
- A projectile is shot from the ground at a velocity of #84 m/s# and at an angle of #(7pi)/12#. How long will it take for the projectile to land?
- How does acceleration change with force?
- Starting from rest, a particle is constrained to move in a circle of radius #4 m#. The tangential acceleration is #a_t = 9 m/s^2#. How long will it take to rotate #45º#?
