Speed at the beginning = zero
Speed after 12 seconds = 45 m/s
Average speed during the 12 seconds = (1/2) · (0 + 45) = 22.5 m/s
Distance covered in 12 seconds at an average speed of 22.5 m/s :
Distance = (speed) x (time)
Distance = (22.5 m/s) x (12 sec)
<em>Distance = 270 meters </em>
Answer:
Explanation:
The hand throwing ball moves on a circular path having radius r = .55 m
mass of ball m = .19 kg
velocity v = 70 mph
= 70 x 1600 / 60 x 60
= 31.11 m /s
centripetal force
= mv² / r
= .19 x 31.11² / .55
= 334.34 N
