Homework Statement Two Questions: 1) A 9.0-kg ball is traveling to the right at 8.0 m/s until it impacts a 3.0-kg stationary ball. After the collision, the 9.0-kg ball is traveling at 5.61 m/s at an angle of 7.8º above the horizontal. Calculate the velocity of the 3.0-kg ball after the...

Homework Statement Using the graph below, what is the magnitude of the impulse provided to a 48 g tennis ball that is swerved due south? Also, What is the velocity of the ball when the racquet and ball separate? Homework Equations p=mv (I think). Fnet x delta Time = P (maybe)?The Attempt...

Thanks, Ill try solving it now

I would assume it is in the 3rd quadrant as well

If sinx = -0.40 and tanx > 0, then secx, to the nearest hundreth, is A) 0.92 B) -0.92 C) -1.09 D) 1.09 So I figured that sin^-1 = -23.57817848, but I don't know how to get sec, can someone help!

alright, I understand! Thanks for the help!

thanks, but for the Ftotal, wouldn't it be equal to m(g-aelevator) since it is going opposed to it?

so the work I did in order to determine the spring constant is as follows: F=KX K=F/X=mg/x=(5.00kg)(9.81m/s2)/0.255m=192N/m I don't understand part b though!

Suppose a spring is attached vertically to the ceiling of an elevator. When a 5.00Kg mass is attached to the spring, it descends a distance of 25.5 cm. a) what is the spring constant of the spring? I found out that it was 192 N/m, so my problem is with part B! b) how far would the spring...
