Q1. A car is travelling with a velocity of + 88.0 km/h. It accelerates at a constant rate of 20 m/s2. If the acceleration lasts for 5.6s, what is the final velocity of the car?
Q2. a.) The light from a 200-W lamp spreads uniformly in all directions. Suppose that 5 percent of the lamp power is converted to light, find the irradiance of the optical E&M wave and the amplitude of the electric field at a distance of 11 m from the lamp.
b.) assume now a 2000-W laser beam is concentrated by a lens into a cross-sectional area of 10^-6 cm^2. Find out the corresponding irradiance and amplitude of E-field and B-field.
