Homework Statement
You are observing a baseball in space, with mass m = 0.144 kg. It is moving past your spacecraft with speed v = 8 m/sec, to the north. Your Acme Tractor Beam can exert 1.2 Newtons of pull force on that baseball.
CALCULATE: How long will it take your Acme Tractor Beam to slow down the baseball to a stop?
Homework Equations
I'm pretty sure I used the wrong equations. For the first time, I used the impulse equation FΔt=Δp
So with this one, to calculate Δp I took mass (.144) x velocity (8m/s) and got 1.152
So 1.152=(1.2N)Δt. I divided both sides by 1.2 to get Δt=.96
This was incorrect.
On the second attempt, I tried another equation. F(m/v) and got .0216. This was also wrong.
The Attempt at a Solution
See above!
Please help me figure out what equation I should be using!
