Ingrid kicks a football with an initial velocity of 12 m/s at an angle of 45° relative to the ground. the horizontal component of the initial velocity to the nearest tenth is m/s.

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

What are the starting materials for nuclear fission? two small nuclei two large nuclei a neutron and a large nucleus a neutron and a small nucleus

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
