A bullet of mass m = 8.00 g is fired into a block of mass M = 190 g that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d = 1.50 m from the bottom of the table. Determine the initial speed of the bullet.
You are designing a testing machine for a golf ball manufacturer. What is the speed of the 0.050 kg golf ball just after being struck by the clubhead
Four charges are located in a plane as follows: q1 = -5 uC at (4,0) m; q2 = -3 uC at (4,4) m; q3 = -4 uC at (0,4) m; q4 = -2 uC at (0,0) m. Find the magnitude and direction of the resultant field at (2,2)
