Questions and Answers

In the context of relative motion, if vBA is the velocity of frame B relative to frame A, what does vBA = 0 imply?

Frame B is stationary with respect to frame A. (correct)

Frame A and Frame B have opposite velocities.

Frame A is stationary with respect to frame B.

Frame A and Frame B have equal velocities.

For a ball thrown vertically upwards with an initial velocity of 30 m/s, what is the maximum height it reaches?

$45$ m (correct)

$30$ m

$60$ m

$15$ m

In projectile motion, what is the equation for the range (R) of an object projected at an angle A to the horizontal?

$R = \frac{u}{g}\sin(A)$

$R = \frac{u}{g}\cos(A)$

$R = u \cdot g \cdot A$

$R = \frac{u^2}{g}\sin(2A)$ (correct)
