Homework Statement The initial velocity of a ball is 1.0 m/s East (E). The final velocity is 1.0 m/s South (S). The change in the velocity of the ball is? Homework Equations (x^2+y^2)^.5 The Attempt at a Solution would it simply be 1.4 southeast?

I had it right the whole time but used the wrong mass..Thanks for the help!

I need to find the force on the wheaties box, not the acceleration.

divide by the masses added?

would it be 27.4 because you subtract forces?

and yes I drew an FBD, and got for the cheerios box F to the right and F of friction to the left. same for the wheaties box

oops sorry. I copy and pasted the question. but basically a 29N force pushes the cheerios box to the right and it hits a Wheaties box that is right next to it, to the right.

Homework Statement a box of Cheerios (mass mC = 1.1 kg) and a box of Wheaties (mass mw = 3.6 kg) are accelerated across a horizontal surface by a horizontal force applied to the Cheerios box. The magnitude of the frictional force on the Cheerios box is 1.6 N, and the magnitude of the...

On a side note, is possible to find k using f=kx?

Homework Statement You use a spring scale to pull a 1.5 kg object on a horizontal frictionless surface with a constant horizontal force of 1.3 N (according to the scale reading). You use a stopwatch to time how long it takes the object, starting from rest, to cover a distance of 2.7 m. What is...

(x+6) lol I have no idea! I know it involves f(1)=6 though

Homework Statement A ball moving with constant speed 1.0 m/s on a horizontal table rolls off the edge of the table. The ball hits the floor 0.50 seconds after leaving the edge. Suppose you roll the same ball on the same table with constant speed 2.0 m/s. After leaving the edge of the table...

(x+1)(x-2)?

yeah the factors are the zeros, right?
