Ed, Edd and Eddy love to play on a seesaw. It consists of a 1-kg board with a length of 8 meters. One day, the other end broke down. They had to cut it by a meter and maintain the pin support in its original position. Then, they tried the seesaw altogether. Ed (m = 55kg) sat on one side about 3m from the pin while Edd (m = 40kg) and Eddy (m = 40kg) on the other side. If Edd was about 3m as well from the pin, calculate the following: The manitude of the reaction force (N) exerted by the pin support on the board. Assume Eddy is in between Ed and Edd. (mass of board = 1kg)
36 (smaller number) and 73 (bigger number)
sum of two numbers = x + x
one number is one more than twice = 2x + 1
other number = x
so it's: 2x + 1 + x = 109
eliminate the 1 by subtracting one to both sides: 2x + 1 - 1 + x = 109 - 1
then combine like terms: 3x = 108
then divide: 108 / 3 = 36. x = 36.
now it looks like this: 36 + 2x + 1 = 109. Now all you need to do is multiply 36 by two then add 1, which would result in 73. Add both of the numbers to make sure
for better experince and so no one can peek
If the object is changing in direction but decreasing in speed its called decceleration
The sports car because it has less mass and less inertia.
