Two trucks drive directly away from oneanother on a straight line, . The trucksdrive with their speeds adjusted precisely so that the center ofmass (CM) of the two trucks remains stationary—that is, thevelocity of the center of mass is zero. The mass and speed of truck 1are m1 = 8400 kg and v1 = 12 m>s, respectively. The mass of truck2 is m2 = 10,200 kg. (a) Is the speed of truck 2 greater than, lessthan, or equal to the speed of truck 1? Explain. (b) Find the speedof truck 2.
A 0.25-kg ball moving in the +x-direction at 13 m/s is hit by a bat. Its final velocity leaving the bat is 19 m/s in the -x-direction. The bat acts on the ball for 0.010 s. Find the average force F exerted on the ball by the bat.
A 7.500 E+3-kg truck moving east at 10.3 m/s collides with a 2.500 E+3-kg car moving west at 35.0 m/s. The collision takes place over a time interval of 0.5 s. The car and the truck stick together after the collision. Find the force (in N) of the car on the truck during the collision. Call this force positive if it points to the east, and negative if it points to the west. (Could you give an explanation on how to transfer/ convert E +3)
