A 1210 kg car and 3620 kg truck undergo a perfectly inelasticcollision. Before the collision, the car was traveling southward at1.80 m/s , and the truck westward at 8.00 m/s.Part A: Find the velocity of the wreckage immediately after thecollision. Enter the x and y components of the velocity separatedby a comma. Assume that the positive x and y axes are directedeastward and northward, respectively.
-Approximately one billion years ago, the Moon orbited the Earthmuch closer than it does today. The radius of the orbit was only24,400 km. What was the orbital period at that time?(for comparison, a day is 8.6 x 10^4 s)
I wrote and adv physics test today and i was stumped by thisquestion...A snail ( with a mass of 0.050kgs) was kicked across the floor. Ithad an instanntanious velocity of 5.5m/s as it left the boot and itslid 10m before coming to a stop. What is the coefficient offriction?Please HELP
