Use the model for projectile motion, assuming there is no air resistance and g 32 feet per second per second. The quarterback of a football team releases a pass at a height of 5 feet above the playing field, and the football is caught by a receiver 25 yards directly downfield at a height of 2 feet. The pass is released at an angle of 35° with the horizontal. (a) Find the speed of the football when it is released....
Use the model for projectile motion, assuming there is no air resistance and g = 32 feet per second per second.
Use the model for projectile motion, assuming there is no air resistance and g = 32 feet per second per second. Determine the maximum height and range of a projectile fired at a height of 4 feet above the ground with an initial speed of 400 feet per second and at an angle of 45° above the horizontal. (Round your answers to three decimal places.) maximum height _______ ft maximum range _______ ft

ornithologists have determined that some species o fly over water than land because air generally rises over land and falls over water during the day. A bird with these tendencies is released from an island that is 3 km from the nearest point B on the shoreline, flies to a point C on the shoreline, and then flies along the shoreline to its nesting area D. Assume that the bird instinctively chooses a path that will minimize its energy expenditure....

8. [Sec. 10.91 A ball is thrown eastward into the air from the origin (in the direction of the positive r-axis). The initial velocity is 50i 80k, with speed measured in feet per second. The spin of the ball results in a southward acceleration of 4 fus2, so the acceleration vector is a-4j - 32k. Find the following (a) The coordinates of the point where the ball lands. (b) The distance (round your answer to the nearest foot) from the...

Many body measurements of people of the same sex and similar ages such as height and upper arm length follow a Normal distribution reasonably closely. Weights, on the other hand, are not Normally distributed. Suppose a survey includes the weights of a representative sample of 548 females in the United States aged 20-29. Suppose the mean of the weights was 161.55 pounds, and the standard deviation was 48.97 pounds. The histogram of the data includes a smooth curve representing an...
