- A ball is tossed straight up from the ground. If it reaches the height of your bedroom window (2.0 m) and then falls straight back down to the ground, (g= 9.8 m/s?; Ignore air resistance and use at least 2 significant figures.) 1. What was its initial velocity? 2. How long is the ball in the air?The motomotorboat starting from rest travels in a straight line on a lake. A.) if the boat aAchieves a speed of 8.0 m/s in 10s, what is the boats average acceleration? B.) then, in 5.0 more seconds, the boat's speed is 12 m/s. What is the boat's average acceleration for the total time?please i need the full answer with the steps
- A swimmer pushes off a wall from rest where she has a constant acceleration of 2m/s2 for 1.5 seconds. She then continues for 10 seconds at constant velocity. At this point, a) How far away from the wall is she if the pool is 50m? b) If she then glides to a stop, what was her deceleration rate? c) Draw the position verse time graph, velocity verse time graph, and acceleration verse time graph. You can assume all accelerations are constant. d) Now take your velocity verse time graph and re calculate the distance covered by the swimmer.A cheetah uses a non-constant acceleration to go from 10 m/s to 25 m/s after 5 seconds. Choose all the following statements that are correct. Than The average acceleration is 3 m/s2. We have enough information to find the distance traveled during this 5 seconds. You can't determine the average acceleration because acceleration is not constant. We have enough information to find the average velocity.A bike messenger travels at a constant v = 10m/s for 5s, changes his velocity to v = −2m/sfor 4s, stops for 10s, then rides at 4m/s for 12s.(a) Sketch a velocity vs. time graph for this motion.(b) Sketch a position vs. time graph for this motion.(c) What is the messenger’s average velocity?(d) What is the messenger’s average acceleration?(e) What is the messenger’s average speed?
