Question

a woman stands on the bank of a frozen lake with a dog by her side. she skims a bone across the ice at a speed of 3ms. the bone slows down with deceleration 0.4 ms square and the dog chases it with acce;eration 0.6 ms square. how far out from the bank does the dog catch up with the bone

Answer 1

are we to assume the velocity is zero when the dog catches it?

Answer 2

@idreamparis ???

Answer 3

yea

Answer 4

its zero

Answer 5

are u gna help me??

Answer 6

what class is this for?

Answer 7

mechanics

Answer 8

its math

Answer 9

its more physics, this is newtons equations for motion, it just really seems we are not given all the information needed. We have only one variable for the dog and this is acceleration, so we assume v_0 is 0, but we also have v at 0 because you said it was... with no time, and nothing else on the dog I dont see how this is possible.

Answer 10

are you told which equations to use?

Answer 11

ut+0.5at (t is squared)

Answer 12

for the bone

Answer 13

and 0.5bh for the dog

Answer 14

u = ? b = ? h = ?
sorry i use different variables for things

Answer 15

its fine

Answer 16

so u is ending vilocity? what is h and b?

Answer 17

height and base

Answer 18

we have to sketch a graph

Answer 19

and find the area of the trianglee

Answer 20

triangle????? I thought the dog was next to her and chased a bone. This has nothing to do with a triangle. Please try to explain everything. Like when we ask if there is more information, tell us about equations given, and triangles...... im wasting my time.
