Please help me out, asap! :-) Thank You very much... A particle accelerates from rest with an acceleration of 3m/s^2 to a speed V. It continues at this speed for time T and then decelerates to rest at 1.5m/s^2. The total time for the motion is 1 minute and the total distance travelled is 1km. Find the value of V.Please help me out, asap! :-) Thank You very much...

Answers

Answer 1

Answer: Well if all you're looking for is speed, then it should be about 17m/s because speed is distance/time, so if you convert 1km/min to m/s then you get 1000/60, and that equals 16.66..., rounded equals 17m/s. Hope I helped!

Find the length of side a. Round to the nearest tenth.A) 12

B) 378.4

C) 18.3

D) 19.5

Answers

Answer:

D) 19.5

Step-by-step explanation:

The law of cosines gives you the relation ...

a² = b² + c² - 2bc·cos(A)

Substituting the given values, you have ...

a² = 13² + 11² - 2·13·11·cos(108°) ≈ 378.379

a ≈ √378.379 ≈ 19.452 . . . . take the square root

a ≈ 19.5
