Velocity and final displacement are both positive, which means they are in the same direction. The equation x=x0+¯vtx=x0+v¯t gives insight into the relationship between displacement, average velocity, and time. It shows, for example, that displacement is a linear function ...
A cannonball is fired with a velocity of 10 m/s upward, and 30 m/s north. In what direction is the cannonball fired? Do all planets undergo retrograde motion as seen from Earth? Two equal masses travelling at velocities of 4 m/s and -2 m/s collide by direct impact...

A velocity of 145 m/s is about 522 km/h, or about 324 mi/h, but even this breakneck speed is short of the record for the quarter mile. Also, note that a square root has two values; we took the positive value to indicate a velocity in the same direction as the acceleration. ...

Using the same assumptions as in subsection 3.2.1, the vehicle equations of motion in basic plane motion inclusive of the motion in longitudinal direction can be expressed by the following equations: (7.1)m(dudt−vr)=2Xf+2Xr (7.2)m(dvdt+ur)=2Yf+2Yr (3.5)′′Idrdt=2(lfYf−lrYr)...

Relates how much lateral acceleration results from each degree of whole vehicle side-slip. Looking at Fig. 5.20 and remembering that the force that produces this lateral acceleration comes from the slip angles at the tyres, we can see that the force always acts in the opposite direction to whi...
Explain why centripetal acceleration changes the direction of velocity in circular motion but not its magnitude. An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its x-coordinate is 2.73 cm. If its x-coordinate 1.85 s later ...
