Ok thank you, I got it now

dy = (vy)(t) + (.5)(a)(t) 1.3 = v1(sin 45)t + .5(9.8)t^2 from here can I just sub in v1=dx/cos 45(t)? If I do, I get the spring constant to be 9 (correct answer is 6) ;/

Homework Statement A spring loaded gun fires a 0.56g ball at an angle of 45 degrees from a horizontal lab bench at a height of 1.30m. The ball strikes the floor 5.64m horizontally (range) from the point of release. If the spring is compressed by 6.50 cm, what is the gun's spring constant...

alright thank you, solved :D

ok well based on what you said: split into x and y and find average i came up with this diagram: http://img132.imageshack.us/img132/3949/diagram.jpg I used the previous values (60), (35) to create the x and y for the purple triangle and finally finding the average speed represented by the...

Homework Statement a car is moving forward at 60 km/h [E 45° N], executes a turn and is now moving at 35 km/h [N 80° W]. If the turn takes 8 seconds to complete the turn what is the average acceleration of the car in m/s? Homework Equations v2 = v1 + a(t) The Attempt at a Solution v2 = 35...
