There is a popular game in the past where children sit on areca leaves and slide down from a higher surface to a lower surface, for example from the top of a small hill. The total mass of the frond and a childern is 67 kg and descends with an initial velocity of 43.3 m / s (assuming there is no friction between the frond and the soil). If then a force slows the movement of the fronds so that it stops with a constant deceleration of 2.3 m / s^2.
a. What is the magnitude of the force in units of N?
b. What is the distance in meters during deceleration to stop?
c. How much work in Joules does the force do to the midrib and child?.

C++ PLEASE In the children’s game, Duck, Duck, Goose, a group of children sit in a circle. One of them is elected “it” and that person walks around the outside of the circle. The person who is “it” pats each child on the head, saying “Duck” each time, until randomly reaching a child that the “it” person identifies as “Goose.” At this point there is a mad scramble, as the “Goose” and the “it” person race around the circle. Whoever...

In this game, two players sit in front of a pile of 100 stones. They take turns, each removing between 1 and 5 stones (assuming there are at least 5 stones left in the pile). The person who removes the last stone(s) wins. Write a program to play this game. This may seem tricky, so break it down into parts. Like many programs, we have to use nested loops (one loop inside another). In the outermost loop, we want to...

Children are playing a game of ice hockey on a frozen lake. One of the children throws a 1200g water bottle with velocity 0.4 m/s to another kid, weighing 41 kg, sitting motionless on the ice who catches the bottle 0.2 m from their COM at angle of impact of 12 degrees. The child on the ice has a center mass moment of inertia of 38 kg m^2. Assuming the ice is perfectly friction-less, answer the following. 1.) How does...

Blackjack, or 21, is a popular casino game that begins with each player and the dealer being dealt two cards. The value of each hand is determined by the point total of the cards in the hand. Face cards and 10s count 10 points, aces can be counted as either 1 or 11 points, and all other cards count at their face value. For instance, the value of a hand consisting of a jack and an 8 is 18; the...
