A5.5-hc point charge is located at x-0.9 m, y3.4 m, and a -3.9-hc point charge is located at x- 2.1 m, y 2.2 m (a) find the magnitude and direction of the electric field at x3.3 m, 0.9 m. magnitude direction kn/c (b) find the magnitude and direction of the force on a proton at x 3.3 m, y-0.9m

Acar accelerates from 5.0 m/s to to 11 m/s at a rate of 3.0 m/s^2. how far does it travel while accelerating? 20m 117m 43m 16m

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s.a. determine jay’s mass.b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)
