A projectile launched vertically from the surface of the Moon rises to an altitude of 275 km. Part A What was the projectile's initial speed?

A ball A is thrown vertically upward from the top of a 36-m-high building with an initial velocity of 6 m/s . At the same instant another ball B is thrown upward from the ground with an initial velocity of 21 m/s. Part A Determine the height from the ground at which they pass. Express your answer to three significant figures and include the appropriate units. h = Part B Determine the time at which they pass. Express your answer to three significant figures and include the appropriate units. t =

A 4He nucleus (atomic weight 4)moving with speed v breaks up into a neutron (atomic weight 1) anda 3He nucleus. The neutron moves off at right angles to theoriginal 4He as shown. If the neutron speed is 3v, the final speed of the 3He nucleus is (a) v. (b) √(7/3)v. (c)4v/√3. (d) √(13/3)v. (e) 5v/3.

Principle of Linear Impulse and Momentum for a System of Particles To apply the principle of linear impulse and momentum to a system of particles. Integrating the equation of motion, as applied to all particles in a system, yields ∑mi(vi)1+∑∫t2t1Fidt=∑mi(vi)2 where mi is the ith particle's mass, vi is the ith particle's velocity, and Fi is the external force that acts on the ith particle. This relationship states that the sum of the initial linear momenta, at time t1, and the impulses of all the external forces acting between times t1 and t2 is equal to the sum of the linear momenta of the system, at time t2. If the system has a mass center, G, the expression becomes m(vG)1+∑∫t2t1Fidt=m(vG)2 This expression allows the principle of linear impulse and momentum to be applied to a system of particles that is represented as a single particle.   Two blocks, each of mass m = 6.90 kg , are connected by a massless rope and start sliding down a slope of incline θ = 36.0 ∘ at t=0.000 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…

The tank is to be placed on a hill that is 1 km high above the ground. The enemy’s base is located at a horizontal distance of 10 km away and it is in a valley 0.5 km below the ground. Air resistance is neglected. Gravitational acceleration is constant and equal to 9.8?/?2 downwards. If the bomb is to be fired perfectly horizontally, what should the launching speed of the bomb be in order to hit the target? What is the duration it would take the bomb to hit the target? Find x(t) and y(t). Consider the initial location of the tank to be (0, 1 km)? Draw the trajectory of the bomb (x and y coordinates). Indicate clearly the value of x (horizontal displacement) when the bomb reaches the ground level. 5.     Draw the (?), ??(?), and ??(?) vertical above each other. Indicate key values on the graphs such as the start, the end, the maximum, the minimum and the x and y intercepts. PART 4 and 5 PLEASE.

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