Question

with r in meters, t in seconds, and A, B, and C positive constants. If the object is a meteorological missile of mass m, what are the (a) y and (b) z components of its linear momentum, and what is (c) the magnitude of the net force on it? Express your answer in terms of the variables given.

An object is tracked by a radar station and found to have a position vector given by hat{k}, with r in meters, t in seconds, and A, B, and C positive constants. If the object is a meteorological missile of mass m, what are the (a) y and (b) z components of its linear momentum, and what is (c) the magnitude of the net force on it? Express your answer in terms of the variables given. hat{j} +C (t) vec{r}= (A-(B/2)(t^2))

Explanation / Answer

V = dr/dt =( A - B/2 )*2t j + C k


a) Py = m*( A - B/2 )*2t

b) Pz = mc


c) a = dV/dt = (A-B/2)*2 j = 2A - B j


F = ma = m*(2A-B) j
