It depends on the bowler.
One of the fastest ball speeds in the world belongs to two-hander Jason Belmonte of Australia; on certain spare tries, his ball has been clocked exceeding 35 mph.
However, a more reasonable speed for an adult male league bowler would be about half that, or 16-18 mph.
'Change up' is another name for a 'slow ball'. Where a fast ball may be thrown around 90 or so MPH, a change up would be thrown in the 75-80 MPH range. It is thrown with the same motion as a fast ball and is used to fool the batter into swinging early at the pitch.
A bowling ball has more momentum. You cannot throw it as fast, but a tenpin ball weighs 16 pounds and a baseball only 1/3 pound. Momentum is mass times velocity and if you throw the bowling ball at 10 mph but the baseball at 90 mph the bowling ball still has much more momentum.
69 mph It can be any speed but probably about 60 mph
Doppler effect : we can measure the speed of ball Doppler principle .we transmit continuous pulse at ball at instant that echo reflect that change in trasmiting and receiving frequncy we can calculate the speed of ball.
Tiger Woods' ball speed is 170 MPH.
The best information I have came from a short film biography that stated in 1941 his fast ball speed was estimated by comparison with a speeding motorcycle going 86 mph. It was estimated he reached 104 mph. However, in 1946 radar guns were available. His fast ball was measured at 107.9 mph. Pretty fast. Claim is that his fast balls frequently measured over 100 mph during regular games. In a film biography of Bob Feller it is said in 1941 his fast ball was estimated at 104 mph. However, in 1946 when radar guns were available his fast ball was clocked at 107.9 mph. Pretty fast. He frequently exceeded 100 mph in regular games.
The force of the bowling ball colliding with the golf ball causes the golf ball to be redirected in an elastic collision. How fast either travels depends on the friction of the surface and the angle of contact with the bowling ball.Comparative Masses and EnergyIn the collision between a golf ball and a bowling ball, the fact that the bowling ball continues to move (although possibly changed in direction) is a function of the comparative masses of the two. The bowling ball is much more massive, so at normal velocities its kinetic energy exceeds the kinetic energy of the golf ball. In order to "stop" the bowling ball, the golf ball would have to make a perfectly aimed collision, and have a much higher velocity. Quantitatively, the velocity of the golf ball would have to be the inverse ratio of the ratio of the masses of the two balls, so that the kinetic energy (mass times velocity) is equal and in the opposite direction.Example : Golf ball at 45 g, ten pound bowling ball at 4500 g -- the golf ball would have to move at 100 times the velocity of the bowling ball to counteract its kinetic energy. If the bowling ball rolls at 2 m/sec, the golf ball would have to travel at more than 200 m/sec (720 kph or 447 mph), about 3 times a ball's normal velocity off the face of a golf club.
