A player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 26 m/s. What is the vertical velocity component of the ball to the nearest m/s?

Transmission Lines and Health. Currents in dc transmission lines can be 100 A or higher. Some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers.

The velocity of a particle moving along the x axis is given by vx = a t - b t3 for t > 0, where a = 27 m/s 2, b = 3.1 m/s 4, and t is in s.

Three resistances 2 ohm, 3ohm and 5 ohm are connected in parallel and a potential difference of 20V is applied across the terminals of combination. The potential difference across 3 ohm resistance is:
