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.

Answer Section#

  • \(27.1 \, \rm{m/s} \; \hat{x}\)

  • \(8.59 \, \rm{m/s} \; \hat{y}\)

  • \(-8.59 \, \rm{m/s} \; \hat{y}\)

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

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

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

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

  • \(0 \rm{m/s}\)
