A punter wants to kick a football so that the football has a total flight time of 4.70s and lands 57.0m away (measured along the ground). Neglect drag and the initial height of the football. - How long does the football need to rise?

- What height will the football reach?

- With what speed does the punter need to kick the football? (vertical component, horizontal component, and vector magnitude)

- At what angle (θ), with the horizontal, does the punter need to kick the football?

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.

Aplayer uses a hockey stick to push a puck at a constant velocity across the ice. the weight of the puck is 170 n. the coefficient of friction is 0.0600. with what force must the player push the puck so that his force just equals the frictional force? 28.3 n 0.999 n 0.102 n 0.0104 n
