Q1. An antelope moving with constant acceleration covers the distance 79.0 m between two points in time 6.70 s. Its speed as it passes the second point is 16.0 m/s. What is its speed at the first point?
Q2. A small object with a mass of 360 mg carries a charge of 30.0 nC and is suspended by a thread between the vertical plates of a parallel-plate capacitor. The plates are detached by 2.40 cm. If the thread makes an angle of 17.0° with the vertical, what is potential difference between the plates?
