A projectile is launched on a horizontal plane with a speed of 30 m/s and an angle of 45° with the horizontal. The projectile explodes 1.5 seconds after launch, splitting into 2 parts. The first part, with 1/3 of the total mass, lands exactly at the origin of the launch. How far from the launch point will the second part fall?
A puck of mass m = 80.0 g and radius r= 4.00 cm glides across an air table at a speed v = 1.5 m/s. It makes a glancing collision with a second puck of radius R = 6.00 cm and mass M = 120 g (initially at rest) such that their rims just touch. Because their rims are coated with instant-acting glue, the pucks stick together and rotate after the collision. a) What is the angular momentum of the system relative to the center of mass? b) What is the angular speed about the center of mass? (a: 7.2E-3 kgm/s, b: 9.47 rad/s)

Some asteroids pass very close to the Earth. Scientists are planning methods to deflect asteroids, to prevent them hitting the Earth. One method would involve colliding a spacecraft into the surface of the asteroid, to change the path and speed of the asteroid. The spacecraft would remain joined to the asteroid after the collision. (a) This collision method is modelled for a spacecraft travelling in a direction at 90° to the path of the asteroid. Sketch a labelled vector diagram to show the momenta of the bodies before and after the collision.(b) Show that the momentum of the spacecraft is about 107 Ns. mass of spacecraft = 920kg speed of spacecraft = 12000ms –1(c)Show that this collision method causes the asteroid to change its direction through an angle of about 10–7 radian. momentum of asteroid = 7.6 × 1013Ns (d) After the collision, the asteroid and spacecraft remain joined and move together. Calculate the component of their velocity at 90° to the original path of the asteroid…
A disk of mass m₂ = 70.0 g and radius ₁ = 4.50 cm slides on a frictionless sheet of ice with velocity v, where v = 13.00 m/s, as shown in a top-down view in figure (a) below.

Four particles at the corners of a square with a side length L=5.00m are connected by massless rods. The particle masses are m1= m4=6.00kg and m2= m3 = 14.0 kg. Pairs of particles with equal masses are located at opposite corners of the square. Find the moment of inertia of the system about the z-axis that passes through a corner of the square where the particle has a mass of m=14.00kg.
