Ok! You're right! The objects stick together after a perfectly inelastic collision. So the mass to consider is 6 kg istead of 2. This leads to a greater force of 1302 N... I'm going to draw a free body diagram and post it as soon as I can because I'm not figuring it out :-(

The masses after the collision move with the same velocity, but I don't know the direction. I supposed the direction was opposite one to each other and I decide to use just the mass of the pole to compute the force.

Because I thought that the penetration is due only to the mass of the pole... What do you think about that?

Well, that value for the acceleration is the value I got, but I'm not completely sure It's correct... what do you think about my resoning?

To find the acceleration I've used the equations for decelerated motion: v = v_0 - at and s=v_0t - \frac{1}{2}a t^2 expressing the time t from the first equation, the second equation becomes: s=\frac{v_0^2}{2a} with a inverse function the acceleration is equal to a=\frac{v_0^2}{2s} The value...

Hello everyone, here's the problem Homework Statement A pole with mass m2 = 2 Kg is planted on the ground with a consecutive hammer hits. The hammer ha a mass m1 = 4 kg and is dropped from 1 meter upon the pole. With a single hit the pole penetrate the ground of 2 cm. Find: a) the total...

I used Pitagora theorem to get the value of 54 km/h that is 15 m/s, but the direction of the vector is north-west and not south-west.

Homework Statement A car is moving toward north with a speed of 35 km/h. A truck travels toward west with a speed of 42 km/h. Which is the speed of the caravan according to the car's driver? Homework EquationsThe Attempt at a Solution The solution given by the book is 15 m/s with direction...

Hi everyone, I'm interested in physics as amateur and I'd like to improve my knowledge in this matter. I hope to receive help and help everyone else need some advice (if I can ;-)) Thanks for accepting me here. Roberto
