- A hiker gets lost in a forest. He walks half-way around a circle with a radius of 2.1 km in 2.0 hours. a) What distance did he walk? b) What was his average speed? c) What was his displacement? d) What was his average velocity?) An object follows as shown below. What is the displacement from the last point to the starting point? Express your answer (a) in unit vector notation, and (b) as a magnitude and direction.The acceleration of an object moving in a strange way has been modelled as a = e^x x.A) use integration by parts to find an equation to model the velocity v if v = ∫ e^x x dx (the x is the letter x not multiplication)B) is the problem any different if you find v = ∫ xe^x dx?
- Mr. Brown takes a walk in the park. He first travels 600. m NW and then turns and walks 800. m @ 20.0° WoS. What is his overall displacement of his walk? Use the triangle method to solve this. Should you use the component method, I will award zero points. I know the answer, I just don’t know how to get it. Answer: 771 m @ 25.1° SoW Thanks!!An equation describing displacement (in meters) as a function of time (in seconds) of a rocket propelled motorcycle moving up a hill is given by: x(t) = 13.5t – 0.5t³ + 7 Where 01/3 SS For the given vectors V₁ and V₂ of Prob. 1/2, de- termine the magnitude of the vector difference V' =V₂ - V₁ and the angle, which V' makes with the positive x-axis.

V. o h d The top of a pool table is a height h = 3.25 ft from the floor. If a player's ball lands a distance d 14.75 ft from the table edge, what is her break shot speed vo? 12.3 Vo = mph Incorrect At what speed v did her pool ball hit the ground? 4.21 mph = Incorrectmdr.4A woman stands at the edge of a cliff and throws a rock horizontally over the edge with a speed of v, = 19.5 m/s. The rock leaves her hand at a height of h = 49.0 m above level ground at the bottom of the cliff, as shown in the figure. Note the coordinate system in the figure, where the origin is at the bottom of the cliff, directly below where the rock leaves the hand.
