SPH4U0: Momentum and Fields Take-Home Assignment Name: 1. While talking about the conservation of momentum and kinetic energy, distinguish between a perfectly clastic collision and a perfectly inelastic collision. [C4] 2. Compare and contrast the gravitational field, electric field, and magnetic field. [C6] 3. A sedan collides with a truck at an intersection. The car, of mass 1.8 x 10' kg, is travelling at 32 km/h [S]; the truck, of mass 2.2 x 10" kg is travelling at 52 km/h [E]. Assuming the collision is perfectly inelastic, determine their velocity just after the collision. [A6] 4. Consider an asteroid in a circular orbit of 5.26 x 10" m, orbiting our Sun. a. Calculate the speed of the asteroid [A3] b. Calculate the period of the orbit in Earth years. [A3]
