Answer:
3,237.78N
Explanation:
According to Newton's second law of motion
F = mass * acceleration
Since a = v-u/t
F = m(v-u)/t
Given
Mass m = 0.155kg
v = 50.0m/s
u = -44.0m/s
Time t = 0.00450secs
Substitute
F = 0.155(50-(-44))/0.00450
F = 0.155(50+44)/0.00450
F = 0.155(94)/0.00450
F = 14.57/0.00450
F = 3,237.78N
hence he hit the baseball with a force of 3,237.78N
Answer:
C
Explanation:
Its because electron does its thing with energy to
its orbital
The average speed you need to maintain is 0.33 miles per minute.
The average speed is the speed that you maintain throughout the journey. It is obtained as; Total distance covered/Total time taken
If we have the following information from the question;
Distance covered = 5 miles
Time taken = 15 mins
Then it follows that;
Average speed = Distance/time
Average speed= 5 miles/15mins
Average speed = 0.33 miles per minute.
