Question 14 8 pts 1. A car's specifications state that its weight distribution is 53 percent on the front tires and 47 percent on the rear tires. The wheel base is 3.46 m. Where is the car's center of mass? (HINT: let the center of mass be x from the car's front. Let the car's weight be F3) (2 pts) 2. A CD-ROM has a spiral track that starts 2.3 cm from the center of the disk and ends 5.5 cm from the center. The disk drive must turn the disk so that the linear velocity of the track is a constant 1.9 m/s. Find the following. 1. the angular velocity of the disk [in rad/s and rev/min) for the start of the track (1 pt)I 2. the disks angular velocity at the end of the track (1 pt} 3. the disks angular acceleration if the disk is played for 76 min (1 pt} 3. A steering wheel is rotated through 123. as shown. Its radius is 22 cm. How far would a point on the steering wheel's edge move? (2 pts) Question 1 A com pact car, with mass 725 kg, is moving at 115 km/hr toward the east. What is the magnitude and direction of its momentum? enter direction x 10" kg'm/S (enter in scientic notation, number then exponent} A second car with mass of 2175 kg has the same momentum. What is its velocity? enter direction enter magnitude of velocityr in km/h Question 2 4 pts The driver of the compact car in the previous problem suddenly applies the brakes hard for 2.0 s. As a result, the average force of 5.0x10 N is exerted on the car to slow it down. What is the change of momentum, or equivalently, what is the magnitude and direction of the impulse of the car? enter direction here enter magnitude of impulse here in scientific notation x10^ N*s What is the momentum and velocity of the car after the 2.0 s of braking? enter direction of the momentum here enter final momentum here in scientific notation X10^ kg*m/s enter direction of velocity here enter velocity in km/h (round to a whole number, no decimals)Question 3 7. A baseball pitcher can throw a 132 km/h {82 mph) curve ball that rotates about ELEM\")2 rpm. What is the angular velocity of the thrown ball? The pitcher's throwing motion lasts about 0.15 s. and the moment of inertia of the ball is 3.0x10'5 kgrnz. What average torque did the pitcher exert on the ball? Enter to (angular velocity} rad/s (enter answer to one decimal place) Enter 1' (torque) N'm [two signicant digits, not scientic notation)
