When the speed of the bottle is 2 m/s, the ke is kg m2/s2. when the speed of the bottle is 3 m/s, the ke is kg m2/s2. when the speed of the bottle is 4 m/s, the ke is kg m2/s2. when the speed of the bottle is 5 m/s, the ke is kg m2/s2. when the speed of the bottle is 6 m/s, the ke is kg m2/s2. instructions in this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. you will use the same mass, 0.250 kg, for each trial, so record this mass in table b for each velocity. then, calculate the expected kinetic energy (ke) at each velocity. use the formula ke = mv2, where m is the mass and v is the speed. record your calculations in table b of your student guide.

Answer from: kavron2322

mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s

kinetic energy is given as

$K = \frac{1}{2}mv^2$

$K = \frac{1}{2}(0.250)(2)^2 = 0.5 J$

2) when speed is 3 m/s

kinetic energy is given as

$K = \frac{1}{2}mv^2$

$K = \frac{1}{2}(0.250)(3)^2 = 1.125 J$

3) when speed is 4 m/s

kinetic energy is given as

$K = \frac{1}{2}mv^2$

$K = \frac{1}{2}(0.250)(4)^2 = 2 J$

4) when speed is 5 m/s

kinetic energy is given as

$K = \frac{1}{2}mv^2$

$K = \frac{1}{2}(0.250)(5)^2 = 3.125 J$

5) when speed is 6 m/s

kinetic energy is given as

$K = \frac{1}{2}mv^2$

$K = \frac{1}{2}(0.250)(6)^2 = 4.5 J$

Answer with Explanation

Record your calculations in Table B of your Student Kinetic energy is the half of the product of mass and square of velocity. If the mass is given which is 0.250 kg. By putting values in the formula we will get values of the kinetic energy of different speeds. Kinetic energy depends upon the mass and velocity of the objects. When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.

MASS(kg) SPEED(m/s) FORMULA KINETIC ENERGY(kgm2/s2)

0.250 2 = ½ (0.250)(2)^2 0.5

0.250 3 = ½ (0.250)(3)^2 1.125

0.250 4 = ½ (0.250)(4)^2. 2

0.250 5 = ½ (0.250)(5)^2 3.125

0.250 6 = ½ (0.250)(6)^2 4.5

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
