rx,ry = ____, ____ m

Part B
v⃗ = (280m/s, 40∘ above positive x−axis)

(Enter your answers numerically separated by a comma)

vx, vy = ____,____m/s

Part C
a⃗ = (5.4 m/s^2, negative y−direction)
Enter your answers numerically separated by a comma.

ax, ay = ___,___ m/s^2

Best Answer for your help :)

Answer 1

(a)

r = 660m , Ø = 43º

 x-component is 

 = 660 cos 43º

 = 660(0.73)

 = 482.69 m

 y-component is  =- r sinØ

 = -660 sin 43º

  =- 660(0.682)

  = - 450.12 m

 ,  =482.69,- 450.12 m

Answer 2

(b)

v = 280 m/s  and Ø = 40º

 x-component is  = v cosØ

 = 280 cos ( 40° )

 = 280 (0.766)

 = 214.49 m/s

 y-component is  = v sinØ

  = 280 sin ( 40° )

  = 280(0.642)

 = 179.98 m/s

vx, vy = 214.49 ,179.98 m/s

Answer 3

(c)

a = 5.4 m/s²  and Ø is along negitive y-direction means Ø = - 90º with respect x-axis

x-component is  = a cos Ø

 = 5.4 cos (-90º)

 = 5.4 (0)

 = 0

 y-component is  = a sin Ø

  = 5.4 sin (-90º)

  = 5.4 (-1)

 = - 5.4 m/s^2

ax, ay = 0, - 5.4 m/s^2

Simply we can say that , there is no x-component because it is going along negitive y-direction
