There is a large crater in Arizona called Meteor Crater. It is estimated that it was formed about 20,000 years ago by a meteorite that had a mass of about 5 x 10^10 kg and was traveling at a speed of 7.5 km/sec. How fast could this meteorite have hit the Earth (whose mass is 6 x 10^24 kg) if we assume a head-on collision?

Consider a race car colliding with the track wall (see figure above). Just before the collision, the car (with the driver) is traveling at a speed vo = 90 m/s along the straight line with an angle of θ1 = 31o from the wall. After the collision, the car is travelling at a speed of v = 46 m/s at an angle of θ2= −12o from the wall. The total mass of the car and its driver is 1542 kg. 1. Calculate the impulse (in kg⋅m/s) due to the collision. 2. Calculate the direction (in degrees) of the impulse. Measure the angle from the +x-axis counterclockwise.
