Now, please check your simulation distance with the range predicted by the range equation. Assuming no air resistance, the range equation gives us the distance an object travels when launched on flat ground: (v² sin 20) part C distance traveled %3D In this equation, v = the launch velocity sin 20 = sin (60 degrees) = 0.866 g = gravity, the exact value used is 9.81 in the default version of the simulation. Please %3D %3D make sure yours was set at this value. Write out your calculation for the distance traveled and paste it The percent error of the range is: |simulated-calculated| calculated · 100% error = part D what is your percent error of the distance traveledE Please type your calculation ·

Part A A cannon tilted up at a 29.0 ° angle fires a cannon ball at 68.0 m/s from atop a 10.0 m -high fortress wall. What is the ball's impact speed on the ground below? ΑΣφ ? Vf = m/s Submit Previous Answers Request Answer

Jae throws a 0,350kg ball so that it is traveling at 7.50m/s toward a wall, approaching the wall at an angle of 35.0⁰ as shown in the figure to the right. After hitting the wall, the speed of the ball is still 7.50m/s but its direction has changed and it is now traveling at an angle of 35.0° away from the wall as shown to the right. a) Sketch on your paper a figure like the one shown to the right and show the vectors for the momentum before impact, PB, the momentum after impact, PA, and use them to find Ap, the change in momentum for the ball. Clearly label each vector. b) Calculate the sign and magnitude of Apx, the change in momentum in the x direction. c) Calculate the sign and magnitude of Apy the change in momentum in the y direction. d) If the collision lasts for 0.150 seconds, find the magnitude of the average force on the ball during the collision. What is the direction of the average force on the ball during the collision? Answer this by showing an arrow and label it as Fave-…

Help! An asteroid is heading towards us at 10 km/s. Scientists decide the best solution is to attach a rocket to the asteroid and fire it to change the trajectory of the asteroid. If the rocket is fired for 8 min, the scientists calculate that the new speed for the asteroid will be 21 km/s and its new trajectory will be at an angle of 25° to its original path. Part A In the process described above, what is the acceleration of the asteroid? Express your answers using two significant figures separated by a comma. Assume that the positive axis is in the direction of the initial motion of the asteroid. The final motion of the asteroid has components in the x and positive y directions only. ax ay = for Part A for Part A undo for Part A redo for Part A reset for Part A keyboard shortcuts for Part A help for Part A Review I Constants m/s2
