An object of mass 100kg is moving with a velocity of 5m/s. Calculate the kinetic energy of that object

Answers

Answer:

1250 J

Explanation:

KE = 1/2(100 kg)(5 m/s)^2

KE = 1250 J

Given m=100kg
V=5m|s
Required KE=?
Solution KE=1/2mv^2
=1/2 100kg(5m/s)^2
=50kg*25(m/s)^2
=1250J

Answers

Answer:

A) y = 1.3x + 10

Explanation:

2 Points on the graph by using x and y values:

(0, 10) and (10, 23)

Slope:

m= (y2-y1)/(x2-x1)

m= (23 - 10)/(10 - 0)

m= 13/10

m = 1.3

Slope-intercept:

y - y1 = m(x - x1)

y - 10 = 1.3(x - 0)

y - 10 = 1.3x

y = 1.3x + 10

Participants enter a research study with unique characteristics that produce different scores from one person to another. For an independent-measures study, these individual differences can cause problems. How can these problems be eliminated or reduced with a repeated-measures study? Check all that apply. In a repeated-measures study, individual differences do not add to the variance of the scores because the same participants are used in all treatment conditions. In a repeated-measures study, you eliminate extraneous changes to the individuals in the sample over time. In a repeated-measures study, both samples consist of the same individuals, eliminating systematic differences between the two samples, which bias the results. In a repeated-measures study, you eliminate the need for the population distribution of difference scores to be normal.
