Question 179: Motion in 2D & Vectors

Question

The velocity of a projectile at the initial point A is $$\left( {2\widehat i + 3\widehat j} \right)$$ m/s. It's velocity (in m/s) at point B is

Accepted Answer

At point B X component of velocity remains
unchanged while Y component reverses its
direction.
$$ 	herefore $$ The velocity of the projectile at point B is
$$2\widehat i - 3\widehat j$$ m/s.

Answer

$$2\widehat i - 3\widehat j$$

Answer

$$2\widehat i + 3\widehat j$$

Answer

$$-$$$$2\widehat i - 3\widehat j$$

Answer

$$-$$$$2\widehat i + 3\widehat j$$
