Answer:

Correct answer:  y = 6.43 units

Explanation:

Given:  the length of the vector  l = 10 units , angle that closes a vector with a positive direction to the x axis α = 40°

The vector forms a rectangular triangle with coordinate axes

sin α = y / l  ⇒ y = l · sin α = 10 sin 40° = 10 · 0.643 = 6.43 units

y = 6.43 units

TiliK225 [7]

Answer:

time taken = 7.514 seconds

\sf{acceleration} =  \dfrac{\Delta v}{\Delta t} = \dfrac{final \ speed - initial \ speed}{time \ taken}

Here given:

  • acceleration: 1.77 m/s²
  • final speed: 24.4 m/s
  • initial speed:  11.1 m/s

using the given formula:

\hookrightarrow \sf{1.77}  = \dfrac{24.4 - 11.1}{time \ taken}

\hookrightarrow \sf{time \ taken}  = \dfrac{24.4 - 11.1}{1.77}

\hookrightarrow \sf{time \ taken}  = 7.514 \ seconds
