The fast server in women's tennis is Venus Williams, who recorded a serve of 130 mi/h (209 km/h) in 2007 If her racket pushed on

the ball for a distance of 0.11 m, what was the average acceleration of the ball during her serve?

209 km/h = 58.0 m/s

2as = v² - u²
Assuming the ball started from rest,

a = (58)² / 2 x 0.11

a = 15,290 m/s²

The literary movement with which Wilde is most closely associated is Select one: a. romanticism b. existentialism c. Art for art
jeyben [28]

Answer:

Correct answer is ''c'' Art for art's Sake

Explanation:

Wilde wrote in the literary movement called Aestheticism during the late nineteenth century. Contrary to popular belief, Wilde did not create the literary movement, but played a role as a leader who promoted the movement. While Wilde was a college student the works of Algernon Charles Swinburne and Edgar Allan Poe influenced his own writing style. Also, the English essayist Walter Pater helped to form Wilde's humanistic aesthetics.

The philosophical foundations of Aestheticism come from Immanuel Kant. He formulated the idea of "art for art's sake". He believed that art was to be enjoyed for its own beauty regardless of social or moral concerns.

2)It is known that the connecting rodS exerts on the crankBCa 2.5-kN force directed down andto the left along the centerline ofA
11111nata11111 [884]

Answer:

M_c = 100.8 Nm

Explanation:

Given:

F_a = 2.5 KN

Find:

Determine the moment of this force about C for the two cases shown.

Solution:

- Draw horizontal and vertical vectors at point A.

- Take moments about point C as follows:

                        M_c = F_a*( 42 / 150 ) *144

                        M_c = 2.5*( 42 / 150 ) *144

                        M_c = 100.8 Nm

- We see that the vertical component of force at point A passes through C.

Hence, its moment about C is zero.
