SITUATION 5: Billy and Joe are doing science experiments in the skating rink at SM Mall of Asia. Billy of mass equal to 80kg was pushed and slid due east, and Joe with mass equal to 50kg was pushed towards north. After the collision, Billy is observed to move N 37° of E with a speed of 6 m/s. Also, Joe is observed to move at S 67° E with a speed of 9 m/s. If the rink is assumed to be frictionless, By how much did the total kinetic energy of the two people decrease after the collision?

hello help with 5 please, complete solution. 3decimal places, thank youu

SITUATION 1: The angular position, of a 0.45m - diameter drum is given by: Determine: e = (7 rad/,a) t² F- 15 N F2 = 10 N a. The distance that a particle moves from 2s to 6s b. The average angular velocity from 2s to 6s C. The average angular acceleration from 2s to 6s 35 SITUATION 2: For the two forces, determine the magnitude and direction of the net torque about point A. 2 m 3m SITUATION 3: A vertical brass post is 3.75m long and has a diameter of 25 cm. If the brass post is to support a load of 9500 kg, and if Young's Modulus for brass is 9* 1010 Pa g = 9.81 m/,2 (Use Determine: a. The stress in the post b. The strain in the post and neglect the weight of the rod) c. The change in the post's length when the load is applied SITUATION 4: A 40-kg boy is sliding on a horizontal and frictionless surface with an initial momentum of 90 J due east. When t-0, a force, as a function of time, F=8.20t is applied to the boy due west. At what value of t will result in the momentum of the boy 60 J due west? a. b. What is the acceleration of the boy at that time computed in (a)? SITUATION 5: Billy and Joe are doing science experiments in the skating rink at SM Mall of Asia. Billy of mass equal to 80kg was pushed and slid due east, and Joe with mass equal to 50kg was pushed towards north. After the collision, Billy is observed to move N 37° of E with a speed of 6 m/s. Also, Joe is observed to move at S 67° E with a speed of 9 m/s. If the rink is assumed to be frictionless, By how much did the total kinetic energy of the two people decrease after the collision? SITUATION 6: A Land Cruiser having a mass of 1500kg goes through an intersection and is traveling from north to south when it is hit by a Mitsubishi Pajero of mass 2200kg traveling from east to west. The two cars slid as one due to impact and stops 5.39m west and 6.43m south measured from impact point. It is known that the coefficient of kinetic friction between the cars and the road is 0.75. How fast each of the car is traveling before the collision?
