Determine the kinetic energy of a 150 kg roller coaster car that is moving with a speed of 15 m/s

K.E = 19125 j

Explanation:

Given data:

Mass = 150 Kg

Speed of car = 15 m/s

K.E = ?

Solution:

Formula:

K.E = 1/2 (mv²)

K.E = Kinetic energy

m = given mass

V = speed

now we will put the values in formula.

K.E = 1/2 (mv²)

K.E = 1/2 (150 Kg) (15²)

K.E = 1/2 150 Kg × 225 m²/s²

K.E = 0.5 × 225 m²/s² ×150 Kg

K.E = 19125 j

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
