5. A small remote-controlled race car has a mass of 150 grams. If the car starting from rest can reach its maximum velocity of 24 m/s in 4 seconds. What is the force of the race car's motor? (5

0.9 N.

Explanation:

Mass (m) of car = 150 g

Initial velocity (u) = 0 m/s

Final velocity (v) = 24 m/s

Time (t) = 4 s

Next, we shall determine the acceleration of the car. This can be obtained as follow:

Initial velocity (u) = 0 m/s

Final velocity (v) = 24 m/s

Time (t) = 4 s

Acceleration (a) =?

v = u + at

24 = 0 + (a × 4)

24 = 0 + 4a

24 = 4a

Divide both side by 4

a = 24 /4

a = 6 m/s²

Thus, the acceleration of the car is 6 m/s²

Next, we shall convert 150 g to Kg. This can be obtained as follow:

1000 g = 1 kg

Therefore,

150 g = 150 g × 1 Kg / 1000 g

150 g = 0.15 Kg

Thus, 150 g is equivalent to 0.15 Kg

Finally, we shall determine the force of the car as follow:

Mass (m) of car = 0.15 Kg

Acceleration (a) of car = 6 m/s²

Force (F) of car =?

F = m × a

F = 0.15 × 6

F = 0.9 N

Therefore, the force of the car is 0.9 N.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
