Chapter 45 Homework X ii https //www.weba OH10 udent/Assignment Responses/submit?pos 17&dep; 15814258 points OSCOMPhy 1642 WA0 e a. Search In each of the cases shown below, the direction of motion of the object is indicated by the velocity vector v. one or more forces act on the object as dagram. How wil the velocity of the object change in each case in the direction shown in the of motion? Assume the forces shown remain constant in and drection. (a) O magnitude will increase, direction wil be the same O magnitude wil decrease, direction will be the same O magnitude will increase, drection wil change O magnitude wis decrease, direction wil change n magnitude of drection O Ask me anythingExplanation / Answer
(A)
Force F = Fxi
speed v = v0yj
acceleration ax = F/m = Fx/m i
along horizontal
vx = ax*t
vy = v0y
magnitude = sqrt(vx^2+vy^2)
magnitude increases
direction = tan^-1(vy/vx)
direction will change
magnitude will increase , direction will change <<<=====ANSWER
+++++++++++++++++++++++++++++++++++
part(b)
Force F = Fxi
speed v = v0xj
acceleration ax = F/m = Fx/m i
along horizontal
after t time
vx = ax*t
along vertical intial velocity v0y = 0
acceleration a y =
vy = 0
magnitude = sqrt(vx^2+vy^2) = vox + ax*t
magnitude increases
direction = tan^-1(vy/vx) = 0
direction will be the same
magnitude will increase , direction will be the same <<<=====ANSWER
========================
(c)
net Force F = Fxi - Fxi = 0
acceleration ax = F/m = 0
along horizontal
vx = vox
vy = 0
magnitude = sqrt(vx^2+vy^2)
no change in magnitude
direction = tan^-1(vy/vx)
direction will be the same
no change in magnitde , direction will be same <<<=====ANSWER
