A cylindrical blood vessel is partially blocked by the buildup of plaque. At one point, the plaque decreases the diameter of the vessel by 73.0%. The blood approaching the blocked portion has speed ?0. Just as the blood enters the blocked portion of the vessel, what is its speed ?, expressed as a multiple of ?0?

A flash lamp is placed at the center of a solid sphere of dense
flint glass of radius 1.00 m. A second, identical flash lamp is
placed at the center of a solid sphere of quartz also of radius
1.00 m. At the same instant both lamps are turned on, each
producing a flash of white light (that is, light...

Two electric motors are started from rest. One (A) has a constant angular acceleration of 73.3 rad/s2, and the other (B) has a constant angular acceleration of 98.7 rad/s2. Motor B is started 0.550 s after A. a) How long after B starts will it have the same angular velocity as A? b) What is this angular velocity? c) How...

A proton accelerates from rest in a uniform electric field of 660 N/C. At one later moment, its speed is 1.40 Mm/s (nonrelativistic because v is much less than the speed of light). (a) Find the acceleration of the proton. m/s2 (b) Over what time interval does the proton reach this speed? s (c) How far does it move in...
