A problem invovling Force, Impulse, Velocity and Acceleration

AI Thread Summary
The problem involves a 240 kg satellite moving at 6000 m/s that is deflected at right angles after being struck by an object over 0.5 seconds. The key equations to consider are impulse, defined as the product of force and time, and the change in momentum. Since the satellite maintains its speed post-deflection, the impulse needed to change its direction equals the impulse required to stop it. The discussion emphasizes breaking the problem into two parts: calculating the impulse to stop the satellite and the impulse to redirect it. Understanding these concepts will aid in solving the problem effectively.

Homework Statement


Heres the problem i have been given in Grade 11 Physics for homework (keep in mind that i haven't done calculus yet so don't do anything too tricky):

A satellite of mass 240 kg moving in free space at a velocity of 6000m/s is struck by an unknown object which causes it to be deflected onto a new path at right angles to its original direction of motion in 0.5 s. Find the impulse which acted upon the satellite if it continued to move at the same speed after deflection. Diagramativally show the change in direction that would occur.

Homework Equations



I'm pretty sure that the equation Impulse=Force * time or F*t = mass * Acceleration will be in it.
From the word problem i know that:
M= 240kg T= 0.5s and velocity is 6000 m/s

The Attempt at a Solution



I think i need to find the acceleration so that i can find the force and then the impulse but I am not sure how to go about that since the speed is the same after the direction as it is at the start
I know that I = F * 0.5 but I am really not sure how to find the Force
I think that ill be able to do the diagram fine but for the rest a hefty shove in the right direction would be nice. Thanks in advance.

Well... Impulse is Force *time. But it is also the change in momentum of the object.

So the impulse required to stop the object is equal to its mass time its velocity.

This requires a force acting over a certain period of time.

Breaking the question into 2 parts we can imagine that there are two forces acting, one to stop the object and the other to pushe it off at right angles.

First of all there is the impulse required to stop it. This will be equal in this case to the impulse to get it going again at right angles.

Is this helpful?
 
Thanks

Yeah, thanks a heap

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}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
