Question

one of these representations is not like the others. tap on the one that doesnt belong. \the projectile has a zero velocity at the highest location.\

Explanation:

• In projectile motion, the horizontal component of velocity ($v_x$) remains constant (assuming no air - resistance), and the vertical component of velocity ($v_y$) changes due to gravity. At the highest point of projectile motion, the vertical component of velocity ($v_y = 0$), but the horizontal component of velocity ($v_x

eq0$).

• The first statement “The projectile has a zero velocity at the highest location” is incorrect because it implies that the total velocity is zero. In reality, only the vertical component of velocity is zero at the highest point.
• The second diagram (with arrows representing velocity vectors) is correct as it shows non - zero horizontal velocity vectors at all points (including the highest point) and appropriate vertical velocity vectors (upward before the highest point, zero at the highest point, and downward after the highest point).
• The third diagram (with arrows representing acceleration vectors) is correct because the acceleration in projectile motion (neglecting air - resistance) is always \(a=-g=- 9.8\ m/s^{2}\) (vertically downward), which is represented by the vertical arrows of the same length (constant acceleration).
• The table is correct as it shows a constant \(v_x = 33.9\ m/s\) and \(v_y\) changing from \(19.8\ m/s\) (initial) to \(0\ m/s\) at \(t = 2.0\ s\) (highest point) and then becoming negative (downward direction).

Answer:

The statement “The projectile has a zero velocity at the highest location” doesn't belong.
