.Which of the following best describes the momentum of a 1000 kg train rolling to the right at 3 m/s ? a) The train has 3000 kg*m/s of momentum

b) The train has 3333.33 kg*m/s of momentum

c) The train has 3000 kg*m/s of momentum to the right

d) The train has 3000 kg*m/s of momentum to the left

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

amplitude

hope this

answerdmitry mendeleyev made a workable classification of the elements

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
