COMPLETTE ALL THESE PHYSICS PROBLEMS.

YOU ARE REQUIRED TO SHOW ALL OF YOUR WORK, I ALSO WANT A CLEAR WRRITING. LASTLY, MAKE SURE THAT ALL YOUR ANSWERS ARE 100% CORRECT.

UU (Make a formula sheet before you start!) 1. Analyze (describe briey) the motion for each motion graph below: (Right = + ), (i.e., Moving to the Right or Left? Speeding Up or Slowing Down? Acceleration Positive or Negative?) v (mfg) x (m) t(s) p t(s) 2. A hot air balloon is descending at a constant speed of 6.2 m/s. At the altitude of 75.0 111, one of the passengers cuts the rope holding a sandbag attached to the outside of the balloon. The bag goes under free fall motion until it hits the ground. Ignore the air resistance. (a) Draw a simple figure. Choose a coordinate system (direction + origin) and show it in your figure. (b) What is the initial speed of the sandbag relative to an observer on the ground? (c) How long does it take the sandbag to reach the ground? 3. A driver's reaction time may be dened as the short time elapsed from the moment 5. Imagine you are standing at the edge of a 32.0 m cliff and throw a rock straight he sees an obstacle on the road till the moment he applies the break Suppose a upward at 11.5 m/s. The rock goes to a maximum height and then falls back and certain driver whose reaction time is 0.24 s, is driving at 17.5 mls when he sees a deer passes by you all the way to the ground jump and stay on the road at a distance of 61.0 m from the can Assume that the (a) Draw a simple figurer Choose a coordinate system (direction + origin) and show maximum slowing down acceleration for the car is 4.5 III/52. Would the driver be able it in your figure, to stop in time and prevent an accident? (Hint: Draw a gure and calculate the (b) To what maximum height (from the top of the cliff) will the rock reach? (Hint: distance travelled before the car stops!) speed at the highest point?) (c) How long does it take the ball to reach the ground? 4. Two cars, A and B, are approaching each other on a straight road, At t = 0, when the cars are 90 m apart, car A is moving at constant speed of 25 m/s but car B, which is moving at 17 m/s, starts to speed up at a rate of 2.4 mlsz. (a) How long does it take for cars to pass each other? (Treat the cars as particle!) 6. Use the following V vs. t graph for a moving particle to answer the following (b) When that happens, how far car A has travelled? questions: (c) What is the speed of car B at that point? (a) Calculate the total displacement. (Hint: area confined!) (b) Calculate the total distance travelled. (c) Calculate the acceleration at t = 7 s and t = 15 s. (Hint: slope!) V (m/s) t(S)
