2) Two individuals are running for mayor of Tallahassee. You conduct an election survey (N = 561) a week before the election and find that 57% of the respondents prefer candidate A. Can you predict the winner (α = 0.01)? (Hint: Use 50% as the proportion o...

one day, at the high jump mat, Lucy,a 4'4 jumper, asks Georgina, a 5' jumper."When running here,breathing doesn't really count right? I mean we're only going less than 50 meters. What difference does it make if we hold our breath?" Georgina sighs and prep...

A 52kg teen grabs onto a rope swing. The length of rope between the teen and the pivot point above is 4.5m, and the rope makes an angle of 40o relative to vertical. Calculate his change in potential energy as he swings down and out to the point where the...

A 0.1kg ball dropped on the floor hits with a speed of 4.0m/s and rebounds at a speed of 3.8m/s. Calculate the impulse delivered to the ball by the floor.

A 0.005kg bullet is fired at 400m/s straight into a stationary 1.0kg block of wood. The bullet exits the far side of the block and continues on the same straight line. The block also moves off in this same direction with a velocity of 1.2m/s. Calculate th...

A particular trophy has a solid 0.2m radius base with a mass of 1.2kg. Rising up from the center is a 0.01m radius solid rod with a mass of 0.4kg. Centered on top of this is a hollow sphere with a radius of 0.15m and a mass of 0.8kg. Calculate the total m...
