10) positive, positive
Both the time x-component of the velocity will be positive because during the whole positive motion the X component of the velocity is towards right and even constant as the object is moving in rightward dorection and only the v component of the velocity changes.
d) zero, vertical downward. e) zero, horizontal. 10. In ideal projectil the x-component of the velocity...

1.) Vectors Can the x or y component of a vector ever have a greater magnitude than the vector itself has? Yes. The x component can, but the y component cannot. Yes, but only when the x and y components have equal magnitudes. Yes. Both components can. Yes. The y component can, but the x component cannot. No. Neither component can. 2.) A force vector has a magnitude of 370 newtons (N) and points at an angle of 53.0° below...
A ball of mass m moving with velocity v_i_vec strikes a vertical wall. The angle between the ball's initial velocity vector and the wall is theta_i as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is Deltat, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the force exerted on the ball by the...
x.Hm of the motions described below, determine the algebraic sign (positive, negative, or zero) of the xcomponent and y component of velocity of the object at the time specified. For all of the motions, the positive xaxis points to the right and the positive y axis points upward. Alex, a mountaineer, must leap across a wide crevasse. (Intro 1 figure) The other side of the crevasse is below the point from which he leaps, as shown in the figure. Alex...
