By what factor is the ball's speed increased
WebY is a thrust factor F r is the radial load F a is the axial load. Consult the table below for determining values X, Y and e. In all series, the rotational factor V is 1.0 for inner ring rotation and 1.2 for outer ring rotation with respect to load. The factor e (last column) represents the ratio of F a /VF r for which the WebThe centripetal acceleration of the ball can be increased by a factor of 4 by A. keeping the speed fixed and decreasing the radius by a factor of 4. B. keeping the radius fixed and decreasing the period by a factor of 4. C. keeping the speed fixed and increasing the radius by a factor of 4.

WebAn object's speed is increased by a factor of three. How does the object's momentum change? MultipleChoice: 1) It decreases by a factor of three. ... When serving a tennis ball, a player hits the ball when its velocity is zero (at the highest point of a vertical toss). The racquet exerts a force of 525 N on the ball for 4.8 ms, giving it a ... WebDrag force FD is proportional to the square of the speed of the object. Mathematically, FD = 1 2CρAv2, where C is the drag coefficient, A is the area of the object facing the fluid, and ρ is the density of the fluid. Athletes as well as car designers seek to reduce the drag force to lower their race times ( Figure 6.29 ).
