# Hit Baseball#

A baseball is hit at 17.6$$^\circ$$ above the horizontal with a speed of 28.4 $$\rm{m/s}$$.

## Part 1#

Neglecting air resistance, what is the velocity of the ball the instant before it hits the ground? Let up be the positive $$y$$-direction and the ball be hit to the right, which is the positive $$x$$-direction.

• $$27.1 \, \rm{m/s} \; \hat{x}$$

• $$8.59 \, \rm{m/s} \; \hat{y}$$

• $$-8.59 \, \rm{m/s} \; \hat{y}$$

• $$27.1 \, \rm{m/s} \; \hat{x} \; - \; 8.59 \, \rm{m/s} \; \hat{y}$$

• $$27.1 \, \rm{m/s} \; \hat{x} \; + \; 8.59 \, \rm{m/s} \; \hat{y}$$

• $$8.59 \, \rm{m/s} \; \hat{x} \; + \; 27.1 \, \rm{m/s} \; \hat{y}$$

• $$8.59 \, \rm{m/s} \; \hat{x} \; - \; 27.1 \, \rm{m/s} \; \hat{y}$$

• $$0 \rm{m/s}$$
