A child riding a bicycle at 15 m/s accelerates at 3. 0 m/s/s for 4. 0 s. What is the child's speed at the end of this 4. 0 s int
mamaluj [8]

Answer:

The final speed of bicycle would be <u>27 m/s</u>².

Step-by-step explanation:

<u>Given</u> :

  • \small\red\bull Initial velocity (u) = 15 m/s
  • \small\red\bull Acceleration (a) = 3.0 m/s²
  • \small\red\bull Time = 4 seconds

<u>To</u><u> </u><u>Find</u> :

  • \small\red\bull Final velocity (v)

<u>Using</u><u> </u><u>Formula</u> :

\longrightarrow{\pmb{\sf{v = u + at}}}

  • \small\blue\star v = final velocity
  • \small\blue\star u = initial velocity
  • \small\blue\star a = acceleration
  • \small\blue\star t = time taken

<u>Solution</u> :

Substituting the values in the formula to find the final velocity :

\longrightarrow{\sf{v = u + at}}

\longrightarrow{\sf{v = 15 + (3.0 \times 4)}}

\longrightarrow{\sf{v = 15 + (3 \times 4)}}

\longrightarrow{\sf{v = 15 +(12)}}

\longrightarrow{\sf{v = 15 +12}}

\longrightarrow{\sf{v = 27 \:  {m/s}^{2}}}

\star{\underline{\boxed{\red{\sf{v = 27 \:  {m/s}^{2}}}}}}

Hence, the final speed of bicycle would be 27 m/s².

If an angle of a parallelogram is two-third of its adjacent angle, the smallest angle of the parallelogram is.
Harrizon [31]

If an angle of a parallelogram is two-third of its adjacent angle, then the smallest angle of the parallelogram is 72°. Adjacent angles exhibit a common side and a corner point.

Adjacent angles exhibit a common side and a corner point, although they do not overlap.

A parallelogram can be defined as a simple type of quadrilateral having two pairs of parallel sides.

A rectangle can in turn be defined as a parallelogram having four right angles (90°), thereby all rectangles represent quadrilaterals.

The sum of the adjacent angles of a parallelogram is equal to 180°.

In this case, we have  that the sum of adjacent angles >> X + 2/3 X = 180° >> X = 108° >> 2/3 X = 72°
