ANSWER

Fdrag=−0.9 NF_{\text{drag}} = -0.9 \text{ N}. Using F=−bv2=−0.1×32=−0.9F = -bv^2 = -0.1 \times 3^2 = -0.9 N.

Practice questions

1 of 30Practice questions for this set
An object with mass mm is projected horizontally with initial velocity v0v_0 on a surface where the only horizontal force is a resistive force given by F=−kvF = -kv. The velocity of the object as a function of time is v(t)=v0e−kt/mv(t) = v_0 e^{-kt/m}. What is the total distance the object travels as it slows to a stop?
