AI Thread Summary
The discussion revolves around two physics problems involving collisions and forces. The first problem involves a collision between two carts, requiring calculations for average force, the force exerted on Cart A, and the resulting velocity of Cart B. The second problem focuses on a bullet fired from a rifle, asking for the average force on the bullet, the recoil force, and the recoil velocity of the shooter. Participants emphasize the importance of showing attempted solutions to facilitate better assistance. The thread encourages engagement and problem-solving within the physics community.

Can Someone Help With This Simple Problems??

1)

A Dynamics Cart A Of Mass 2.0kg Is Travelling South At 1.5m/s When It Collides With A Second Cart B Of Mass 3.0kg, Which At Rest. Cart A Rebounds With A Velocity Of 0.30m/s North.

A) If The Collision Lasts 0.50s, What Is The Average Force Exerted On Cart A?
B)what Exerts Teh Force On Cart A
C) What Is The Force Exerted By Cart A On Cart B
D) What Is The Velocity Of Cart B After The Collision

2)

a 5.0g Bullet Is Fired From A Rifle With A Muzzle Velocity Of 3.0*10^2m/s North. If The Bullet Takes 5.0 *10 ^-3 S To Travel The Lenght Of The Barrel Of The Gun, Calculate.

A)the Average Force Exerted On Teh Bullet
Bthe Recoil Force On The Shooter And Rifle
C) What Is The Recoil Velocity Of The Shooter If He Is Standing On A Frictionless Surface And Has A Mass Of 40.0 Kg.

oh c'mon... you can solve at least ONE of them. I can't just put 7 approaches to 7 questions.

show that you at least tried

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
