Aroller coaster begins at the top of a hill. if it accelerates at the rate of 2 m/s2 and has a mass of 2000 kg, what net force is acting on it? (f=ma) a) 0.001 n b) 0.5 n c) 1000 n d) 4000 n

the 4th choice is the correct one

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
