✰ <u>Concept</u><u> </u><u>:</u><u>-</u>

⠀

We know that momentum is the product of mass and velocity. Thus, by the following definition, we get :-

⠀

\qquad \maltese \:  \underline{  \boxed{ \purple{ \sf Momentum = Mass \times Velocity }}} \:  \star

⠀

✰ <u>Given</u><u> </u><u>Information</u><u> </u><u>:</u><u>-</u>

⠀

  • A particle has mass 10 kg
  • Moving with velocity 5 m/s

⠀

✰ <u>To Find</u><u> </u><u>:</u><u>-</u>

⠀

  • The momentum of the particle

⠀

✰ <u>Solution</u><u> </u><u>:</u><u>-</u>

⠀

Using the formula from the concept section, we get :-

⠀

\sf \longrightarrow Momentum =10 \: kg \times 5 \:  {m}^{ - 1} ~~~ \\  \\  \\\sf \longrightarrow Momentum = {50~kg \: ms}^{ - 1}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \\   \sf \longrightarrow  \underline{ \boxed{ \frak{ \orange{Momentum = {50 ~kg\: ms}^{ - 1} }}}} \:  \star \:  \:  \:  \:  \:  \:  \\  \\

Thus, the momentum of the particle is 50 kg m/s.

⠀

\underline{ \rule{230pt}{2pt}} \\  \\

Some cities now implement signal lights designed to specifically apply to _____ rather than motorized vehicles.
dmitriy555 [2]

The correct answer is C; Bicycles.

Further Explanation:

In major cities, in the United States, have implemented signal lights specifically designed for bicycle riders. The riders also have their own designated bike lanes in many large cities. Drivers in vehicles, are to give the right of way to people on bicycles.

Bicycle riders are to follow the same laws and laws specifically for the riders or they can face fines and tickets.

A ball is shot at an angle of 45 degrees into the air with initial velocity of 46 ft/sec. Assuming no air resistance, how high d
mestny [16]

Answer:

5.02 m

Explanation:

Applying the formula of maximum height of a projectile,

H = U²sin²Ф/2g...................... Equation 1

Where H = maximum height, U = initial velocity, Ф = angle, g = acceleration due to gravity.

Given: U = 46 ft/sec = 14.021 m/s, Ф = 45°

Constant: g = 9.8 m/s²

Substitute these values into equation 1

H = (14.021)²sin²45/(2×9.8)

H = 196.5884×0.5/19.6

H = 5.02 m.

Hence the ball goes 5.02 m high

A 6kg sled sliding on an icy surface experiences a 6-N frictional force exerted by the ice and the air resistive force of 0.6 N.
White raven [17]

The net force on the sled is 6.6 N pointing backwards, opposite to the direction it's sliding. That's why it's slowing down, and will eventually stop.
