A long jumper leaves the ground at a speed of 11.0m/s. Assuming that his motion Is equivalent to that of a particle, A.) How far does he jump in the horizontal direction if he took off at an angle (i) 30° (ii) 45° (iii) 60° above the horizontalB.) What is the maximum height reached in the 3 cases

ASK TOUR TEACHER PRACTICE ANOTHER As shown in the figure below, cars #1 and #2 are sliding across a horizontal frictionless surface. The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m₁ = 13.5 kg and m₂ = 45.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1 before, during and after the collision. p (kg. m/s) 100 40 Determine the velocity (in m/s) of car #2 before the collision. t(s)

Sweden and Norway are at war over who makes the best pickled herring. You are in charge of a Swedish artillery unit that is trying to shoot at some Norwegians located 1000 meters away at the same height as you are. If we neglect the friction of the air, the cannon ball follows a parabolic trajectory; as you certainly recall from prior courses, a cannon ball travels a distance L = V²sin(2a) 9 where V is the initial velocity, a is the angle of the cannon barrel, and g = 9.8 m/s² is the gravitational acceleration. You realize that you only have two options for how to shoot. Option (I) is to use 1 bag of gun powder, which produces an initial velocity of exactly V₁ = 105 m/s, and to try to set the angle to aI,nominal = 39 degree. Option (II) is to use 2 bags of gun powder, which produces exactly VII = 137 m/s, and to try to set the angle to aII,nominal = 15 degree. If you set the angles exactly to the nominal ones, compute the traveling distances. L₁ = LII = The problem is that the cannon…

In the situation illustrated in the figure below, a small package is deposited by a conveyor belt at point A onto a ramp at theta = 35 degrees degrees to the horizontal with a velocity of 0.5m / s . The distance between points A and Bis 2 m. a)Calculate the maximum value mu k ^ * of the kinetic friction coefficient between the package and the ramp AB for which the parcel reaches point B. b) If the actual kinetic friction coefficient between the package and AB and BCis mu k =0.5 mu k ^ * calculate the distances on the level surface BC at which the package comes to rest. Note: if you haven't been able to solve part a), take the actual kinetic friction coefficient equal to mu_{k} = 0.28

can you pls also draw a picture/representation of the scenario described? Thanks so much!

Mechanical engineering mechanics, Hockey player A carries the puck on his stick and moves in the direction shown with a speed VA = 4.6 m/s. In passing the puck to his stationary teammate B, by what angle a should the direction of his shot trail the line of sight if he launches the puck with a speed of 6.0 m/s relative to himself?
