Okay, so Newton's 2nd Law in terms of momentum is Δp = F Δt , which is also
F Δt = m Δv.
So in isolating velocity from the formula, as the mass decreases, the velocity would increase?
Hey guys!
I was wondering if I could get some help with this question:
A railway freight car that is carrying sand is traveling at a uniform velocity on a straight level track. A leak develops in the flat bottom, and the sand begins to pour out of a hole onto the ground. Assuming there...
I have some questions about this problem too. Okay, I've got that:
Force of buoyancy = Weight (of logs) + Weight (of load/people)
Since each person's mass was 80.0 kg and there are 4 people, I went
Weight (load) = (80.0kg) x (4) x (9.81m/s^2) = 3139.2 N (Force of the load)
and the force...
Hi! I'm not sure where to start on this question and I would be very thankful if somebody could help me on it:
At a mini golf course, a golf ball passes through a windmill. The windmill has 8 blades and rotates at an angular speed of 1.25 rad/s. The opening between successive blades is equal...
