In the figure, two particles are launched from the origin of the coordinate system at time t = 0. Particle 1 of mass m₁ = 6.20 g is shotdirectly along the x axis (on a frictionless floor), where it moves with a constant speed of 12.9 m/s. Particle 2 of mass m₂ = 2.80 g is shotwith a velocity of magnitude 24.2 m/s, at an upward angle such that it always stays directly above particle 1 during its flight. (a) What isthe maximum height Hmax reached by the com of the two-particle system? In unit-vector notation, what are the (b) velocity and (c)acceleration of the com when the com reaches Hmax?x

we have given m1 = 6.20 g = 0.00620 kg v1=12.9 m/s m2=2.80 g = 0.00280 kg v2=24.2m/s

A block of mass m1 = 15.5 kg slides along a horizontal surface (with friction, μk = 0.29) a distance d = 2.65 m before striking a second block of mass m2 = 5.25 kg. The first block has an initial velocity of v = 9.25 m/s. What is the speed of m1, in m/s, right before it collides with m2? Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?
The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at ??,2=17.5 m/s when the eagle swoops down, grabs the pigeon, and flies off. At the instant right before the attack, the eagle is flying toward the pigeon at an angle θ=47.1° below the horizontal and a speed of ??,1=42.1 m/s. What is the speed of the eagle immediately after it catches its prey? Speed: What is the magnitude of the angle, measured from horizontal, at which the eagle is flying immediately after the strike?

A toy rocket operates by having a spring-loaded tube which ejects a small model rocket when released. The spring inside has a spring constant k = 625N/m, the rocket has a mass of 0.100 kg, and the maximum compression of the spring is 0.18 m. Consider the system of the rocket, spring, and the earth. Consider the interval of time between t1, when the rocket is released from the point of maximum spring compression, and t2, the moment when the spring is fully released and the rocket leaves the launcher. List below the types of energy that are changing during this interval and whether the changes are positive or negative. Please explain how you know.

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.62 m/s, and bumper car 2 is traveling 60.0° south of west at 10.00 m/s.
