5a. Three charges q1=0.03 μC, q2=0.02 μC, q3=0.01 μC are located at (0m, 0m), (0.1m,0m) and (0m, 0.2m) respectively. Calculate the potential due to these charges at (0.2m, 0.2m). Use V = k(q1/r1 + q2/r2 + q3/r3) eq. [V= k(q1/r1 + q2/r2 + q3/r3)], each of the distance is between (0.2m...

Assume that a pitcher throws a baseball so that it travels in a straight line parallel to the ground. The batter then hits the ball so it goes directly back to the pitcher along the same straight line. Define the direction the pitcher originally throws the ball as the +x direction. Answer: The...

A block of mass 1.00 \rm kg sits on an inclined plane as shown. A force of magnitude 80.0 \rm N is pulling the block up the incline at constant speed. The coefficient of kinetic friction between the plane and the block is 0.500. The inclined plane makes an angle 60.0 degrees with the...

A 1700 kg sports car accelerates from rest to 95 km/h in 7.0 s. What is the average power delivered by the engine?

Find the work W_1 done on the block by the force of magnitude F_1 = 100 N as the block moves from x_i = -2.00 cm to x_f = 5.00 cm
