Canoeist 1 paddles with a speed of 1.10 $\mathrm{m} / \mathrm{s}$ at an angle of $45^{\circ}$ north of east. Speed and Acceleration are very important in basketball. (The acceleration of gravity on lo is1.80 $\mathrm{m} / \mathrm{s}^{2} . The findings showed that there was a significant relationship between height and speed (rs =-.199, p = .017), as well as speed and agility (rs = .359, p <.000) among male basketball players. Such findings confirm to be very interesting since they hint that even an eventual detection of a slight reduction in speed of kicking in a more aged group (e.g., 17 vs. 15 years of age) should be taken into consideration. James wrote, âA day full of excitement, with no pause, is said to pass âere we know it.â On the contrary, a day full of waiting, of unsatisfied desire for change, will seem a small eternity.â Now, obviously, itâs going to be hard to stop looking at clocks. The "hang time" of a punt is measured to be 4.50 s. If the ball waskicked at an angle of $63.0^{\circ}$ above the horizontal and was caught atthe same level from which it was kicked, what was its initial speed? Therescuers like to step off their helicopter when it is "ten and ten," which means that it is ten feet above the water and moving forward horizontally at ten knots. (b) Where does the ball land in thecase described in part (a)? College - 80%. (a) If a pitch is thrown horizontally with an initial speed of 32 $\mathrm{m} / \mathrm{s}$ , how far does it drop by the time it reaches the catcher? Passing is a two-step process that requires a minimum of two players on the same team to be effective. In Step 2, students should observe the ball in a zigzag path away from the stationary observer. Thus, the horizontal distance to the ball is $5.50 \mathrm{m},$ thedrop height is $4.10 \mathrm{m},$ and the dolphin's launch speed is 12.0 $\mathrm{m} / \mathrm{s}$ . Predict/Calculate A soccer ball is kicked with an initial speedof 10.2 $\mathrm{m} / \mathrm{s}$ in a direction $25.0^{\circ}$ above the horizontal.
