Question

A rock moving in the $+x$ -direction with speed $16.0 \mathrm{~m} / \mathrm{s}$ has a net force applied to it at time $t=0,$ and this produces a constant acceleration in the $-x$ -direction that has magnitude $4.00 \mathrm{~m} / \mathrm{s}^{2}$. For what three times $t$ after the force is applied is the rock a distance of $24.0 \mathrm{~m}$ from its position at $t=0 ?$ For each of these three values of $t,$ what is the velocity (magnitude and direction) of the rock?

Name: A rock moving in the +x -direction with speed 16.0 m / s has a net force applied to it at time t=0, and this produces a constant acceleration in the -x -direction that has magnitude 4.00 m / s^2. For what three times t after the force is applied is the rock a distance of 24.0 m from its position at t=0 ? For each of these three values of t, what is the velocity (magnitude and direction) of the rock?

Step 1

The initial velocity $ v_0 $ is $ 16.0 \, \mathrm{m/s} $ in the $ +x $-direction. The acceleration $ a $ is $ -4.0 \, \mathrm{m/s^2} $ in the $ -x $-direction. The distance $ x $ from the initial position is $ 24.0 \, \mathrm{m} $. Show more…
