- A larger acceleration, which is the change in velocity divided by the change in time is the theta or the angle that it climbs to.
- Secondly the launch velocity is higher or faster and traveles a further distance.
Answer:
Zero, the support force and gravitational force together equal a zero net force
Explanation:
Answer:
The average force is 1578.94 N.
Explanation:
Given that,
Mass of baseball = 150 g
Speed = 45 m/s
Speed of pitcher = 60 m/s
Time = 9.5 ms
We need to calculate the average force
Using formula of impulse
...(I)
....(II)
From equation (I) and (II)
Where, m = mass of baseball
= final velocity
= Initial velocity
= time
Put the value into the formula
Hence, The average force is 1578.94 N.
