Impulse-Momentum Theorem and acceleration

AI Thread Summary
The discussion focuses on applying the Impulse-Momentum Theorem to a problem involving a 3.00 kg object with an initial velocity of 7.00 j m/s and a force of 12.0i N acting for 5 seconds. To find the final velocity, the impulse (force multiplied by time) is equated to the change in momentum. The acceleration can be calculated using two methods: from the change in velocity over time and from the force divided by mass. Participants are encouraged to clarify the application of the theorem for part (a) of the problem. The conversation emphasizes understanding the relationship between force, impulse, and momentum.

Impulse-Momentum Theorem...

Homework Statement


So here's the problem:
a 3.00 kg object has velocity 7.00 j m/s. Then, a total force of 12.0i N acts on the object for 5 seconds.
A.Calculate the object's final velocity using the impulse momentum theorem.
b. calc its acceleration from a = (vf - vi) / delta t.
c. calculate its acceleration from a = F/m

Homework Equations


<given in question>

I really don't know what to use for impulse-momentum theorem in a? Any and all help is appreciated...

Welcome to PF.

F = m*a = m*Δv/Δt

F*Δt = m*Δv = Δp

So in a, you have F and Δt. That gives you Δp
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
