Answer: Option B) 1038J
Explanation:
Given that
Mass of person (m) = 83kg
kinetic energy (KE) = ?
Speed of elevator (v) = 5m/s
Kinetic energy is the energy possessed by a moving object. It is measured in joules, and depends on the mass (m) of the object and the speed (v) by which it moves
i.e K.E = 1/2mv²
KE = 1/2 x 83kg x (5m/s)²
KE = 0.5 x 83 x 25
KE = 1037.5J (Round the kinetic energy to the nearest whole number as 1038J)
Thus, the kinetic energy of the person is 1038 Joules
- Let (X1, Y1) be one end point of the line segment that represents (1,2).
- Let (Xm, Ym) be the coordinates of the midpoint of the line segment which are given as (-1,4).
- Let (X2, Y2) be the other end point which has to be found out.
It then can be stated:
Since, Xm = -1 and X1 = 1 we can write equation (1) as
Since , Ym = 4 and Y1 = 2 we can write the equation (2) as
Therefore the other endpoint of the line (X2, Y2) is (-3 , 6)
Yes they should all be going the same speed.
Hope this helped :)
