Two charges are located in the x x – y y plane. If q 1 = − 2.75 nC q1=−2.75 nC and is located at ( x = 0.00 m , y = 0.600 m ) (x=0.00 m, y=0.600 m) , and the second charge has magnitude of q 2 = 3.40 nC q2=3.40 nC and is located at ( x = 1.30 m , y = 0.400 m ) (x=1.30 m, y=0.400 m) , calculate the x x and y y components, E x Ex and E y Ey , of the electric field, → E E→ , in component form at the origin, ( 0 , 0 ) (0,0) . The Coulomb force constant is 1 / ( 4 π ϵ 0 ) = 8.99 × 10 9 N ⋅ m 2 /C 2 1/(4πϵ0)=8.99×109 N⋅m2/C2 .

The force will determine the acceleration.

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?
