7. 2 football players separated by 42 m run directly toward each other. Football player one starts from rest and accelerates at 2.4 m/s² to the right, and football player, two moves uniformly at 5.4 m/s to the left.
a) How long does it take for the players to collide?
b) How far does each player move?
c) How fast is football player 1 moving on the players collide?

16. An object is pushed along a rough horizon, no surface and released. Its lives for 10.0 seconds before coming to rest and travels the distance of 20.0 cm during the last one .0 seconds of its slide. Assuming the acceleration to be uniform throughout.

18. Of course of 800 Newton is applied to M1 is equal to 60 kg block which is resting against a M2 is equal to 90 kg block. Calculate the action reaction forces between the two blocks if there are forces of friction of F1 is equal to 5.0 N and F2 is equal to 7.0 N.

19. A ball is thrown from the height of 52 m from the top of a building with a velocity of 24 m/s straight up.

20. A Pedestrian is running at his maximum speed of 6.0 m/s trying to catch a bus that is stopped at a traffic light. When he is 16 meters from the bus, the life changes in the bus pulls away from the pedestrian with an acceleration of 1.0 m/s^2.

21. Pushes two large boxes across the floor from rest with an applied force of 160.0 N to the right on the larger box. The boxes are touching. The mass of the larger boxes M1 is equal to 32.0 kilograms and the mass of the smaller box is M2 is equal to 8.0 kg. The fourth of the friction on the large box is 80.0 N and the force of the friction on the smaller box is 20.0 N.

22. An object is pushed from rest across as sheet of ice, accelerating at 5.0 m/s² over 80.0 cm. The object, then slides with the constant speed for 4.0 seconds until it reaches a rough section which causes it to stop in 2.5 seconds.

23. In a physics experiment about is released from rest, and falls toward the ground. The timer was not paying attention but estimates that it took 1.5 seconds for the ball to fall the last 32 m.

Main Remarks & Lessons:

28. (book practice) - check

29. Calculate the acceleration of a vehicle which changes its velocity from 5.0 m/s [W20°S] to 2.0 m/s [E] in a period of 6.0s. (from worksheet) - check

32. You are playing tennis with a friend on tennis court that are surrounded by a 4.8 m fence. Your opponent hits the ball over the fence and you offer to retrieve it. You find the ball at a distance of 12.4 m on the other side of the fence. You throw the ball at an angle of 55.0° with the horizontal, giving it an initial velocity of 12.1 m/s. The ball is 1.05 meter above the ground when you release it. Did the ball go over the fence, hit the fence, or hit the ground before it reached the fence? (ignore air resistance) (challenging questions) - check

33. At snowball is thrown from a height of 2.0 m with a speed of 10 m/s at an angle of 30° above the horizontal. Find its time of flight and range if it strikes a wall of height of 3.0 m.

34. A baseball player makes perfect contact with the ball, striking it 45° above the horizontal at a 1.3 m above the ground. His homerun hit just clears the 3.0 m wall 130 m from home plate. With what velocity did the baseball player strike the ball?

35.

37. A 0.25 kg hockey Park sliding across the ice with an initial velocity of 12 m/s [S] is struck by hockey stick with force of 300 N [N25°E]. If the hockey stick interacts with the puck for 0.20 s, determine the puck’s final velocity.
