A uniform ladder whose length is 4.4 m and whose weight is 490 N leans against a frictionless vertical wall. The coefficient of static friction between the level ground and the foot of the ladder is 0.49. What is the greatest distance the foot of the ladder can be placed from the base of the wall without the ladder immediately slipping?

What is the length x of the side of the triangle below? (hint: use the cosine function)

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

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
