Aprofessional golfer is examining a video of a practice swing. the high‑speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only δ=0.971δt=0.971 ms, and the radar gun clocks the speed of the ball as =161vb=161 mph after it comes off the club. the golf ball has a mass of =45.9mb=45.9 g. what is the magnitude of the impulse imparted to the ball by the club?

In an experiment, how can i change human errors? be specific.

Which form of cell division creates the sperm and egg, resulting in half of the chromosomes as the other cells?

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
