Acart is propelled over an xy plane with acceleration compo- nents ax 4.0 m/s2 and ay 2.0 m/s2. its initial velocity has com- ponents v0x 8.0 m/s and v0y 12 m/s. in unit-vector notation, what is the velocity of the cart when it reaches its greatest y coordinate?

Explanation:

Given:

Let the x and y components of the final velocity of the cart when the cart reaches its greatest y coordinate be respectively.

When the cart reaches its greatest y-coordinate then the y component of its final velocity should be zero,

Let the cart reaches its greatest y-coordinate at time t, then using the following equation:

At this time, the x component of the velocity of the particle is given by

Thus, the velocity of the cart when it reaches its greatest y coordinate, in unit-vector notation, is given by
