Calculate the kinetic energy of a Cheetoh truck (yum) that has a mass of 290kg and is moving at 30m/s

Answer:

The Kinetic energy of the Cheeto truck = 130,500 J

Explanation:

The Formula for Kinetic energy is

K.E = 1/2 x M x V^2

So in this Situation Mass(M) is 290kg

Velocity (V) is 30 m/s

Inputting these values into our equation gives us

K.E = 1/2 x 290 x 30^2

30 times 30 = 900

So K.E = 1/2 x 290 x 900

Simplifing this we get : K.E = 290 x 450

So K.E = 130,500 Kgm^2/s^2

Now the unit's Kgm^2/s^2 scientific name is Joule and symbol (J).

So K.E = 130,500 J

P.S: Oh man, now I have a craving for some Cheetos!

Calculate the average travel time for each distance, and then use the results to calculate.
Eddi Din [679]

The average time that it takes for the car to travel the first 0.25m is 2.23 s

The average time that it takes for the car to travel the first 0.25 m is given by:

t=\frac{2.24 s+2.21 s+2.23 s}{3}=2.227 s \sim 2.23 s

The average time to travel just between 0.25 m and 0.50 m is 0.90 s

First of all, we need to calculate the time the car takes in each trial to travel between 0.25 m and 0.50 m:

t_1 = 3.16 s - 2.24 s=0.92 s\\t_2 = 3.08 s- 2.21 s=0.87 s\\t_3 =3.15 s- 2.23 s=0.92 s

Then, the average time can be calculated as

t=\frac{0.92 s+0.87 s+0.92 s}{3}=0.90 s

Given the time taken to travel the second 0.25 m section, the velocity would be 0.28 m/s

The velocity of the car while travelling the second 0.25 m section is equal to the distance covered (0.25 m) divided by the average time (0.90 s):

v=\frac{d}{t}=\frac{0.25 m}{0.90 s}=0.28 m/s

Sunny_sXe [5.5K]

Answer:

P V = n R T      ideal gas equation

P2 V2 / P1 V1 = T2 / T1    

V2 / V1 = T2 / T1 * P1 / P2 = T2 P1 / (T1 P2)

V2 / V1 = (1.17 T1) / T1 * (P1 / .22 P1)      assuming absolute temp as 1.17 P1

V2 / V1 = 1.17 / .22 = 5.32

V = 4/3 pi R^3 = 4/3 pi (D/2)^3 = 4/3 pi D^3 / 8 = pi D^3 / 6

V2 / V1 = D2^3 / D1^3

D2 = (V2 / V1 * D1^3)^1/3

D2 = 5.32^1/3 * D = 1.75 D      (D1 = D)
