1. How fast must an 823 kg Geo travel
(a) to have the same linear momentum as a 2770 kg Cadillac going 31 km/h
(b) to have the same kinetic energy?
2. A baseball of mass 145 g moves horizontally to the left at 39.8 m/s and is met by a bat of mass 911 g moving horizontally to the right at 31.5 m/s. After the collision the ball leaves the bat moving to the right and upwards at an angle of 30° above the horizontal and with a speed of 42.0 m/s.(a) What is the speed of the bat after the collision?
(b) What is the angle (in degrees) of the bat's velocity after the collision? °
(c) What is the initial kinetic energy of the system?
(d) What is the final kinetic energy of the system?
(e) Is the collision elastic?
