Given that,
Mass of a baseball, m = 0.2 kg
Initial speed of a baseball, u = 30 m/s
Force produced by a bat, F = 2000 N
Final speed of a baseball, v = -50 (negative for opposite direction)
To find,
For how long was the ball in contact with the bat?
Solution,
Let for t seconds the ball is in contact with the bat. The net force acting on the ball is given by :
So, the ball is contact with the bat for 8 ms.
Answer:
q2 = 5.1μC
Explanation:
From a forces diagram we can stablish that:
Fe = T*sin(16) (eq1)
T*cos(16) = m*g (eq2)
Where Fe is the electric force and T is the tension of the string. Solving for Fe:
Fe = m*g*tan(16)
The magnitude of the electric force is calculated as:
Solving for q2:
