To win the game, a place kicker must kick afootball from a point 23 m (25.1528 yd) fromthe goal, and the ball must clear the crossbar,which is 3.05 m high. When kicked, the ballleaves the ground with a speed of 17 m/s atan angle of 55.7° from the horizontal.The acceleration of gravity is 9.8 m/s.By how much vertical distance does the ballclear the crossbar?S.2

Given: Angle of the kick (θ) = 55.7° velocity of the kick (u) = 17 m/s acceleration due to gravity…

Answered: To win the game, a place kicker must…

A daredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 24.0 m/s. A net is positioned a horizontal distance of 49.5 m from the cannon. At what height above the cannon should the net be placed in order to catch the daredevil?
1. Multiplication or division: keep the same number of significant figures in the product or quotient as is in the least precise factor. Examples: 3.1 * 25.6=79.360000... = 79 6.7/981.0=0.0068297655... = 0.0068 keep only 2 significant digits 2. Powers or roots: keep the same number of significant figures as in the original number. Example: Sqrt(38) 6.164414... keep only 2 significant digits = 6.2 (11.6)² = 134.5600000... = 135 Exercises 3. Addition or subtraction: Round off, to the number of decimal places determined by the number with the least number of places beyond the decimal point. Example: 31.5+24.61 +3.28+1.19 +0.762 +0.003 = 61.345 1. 3.9 * 78.9= = 61.3 (correct result) 2. 32.01 +96.321 +36.98 +0.00023 +28.9= 3. 26.9/98 = 4. 421 0.003 =
Find the direction of motion of the two snowballs just before they land with degrees below the horizontal. My answer is -90° and -38.7°, but I'm told that this is incorrect and to check my signs. Changing the signs still results in an incorrect answer.
