Answer:
The distance the mass would stretch it is
The correct option is A
Explanation:
From the question we are told that
The period of the slit is
The acceleration due to gravity is
Generally the period is mathematically represented as
Whee m is the particle and k is the spring constant
making the subject
The weight on the particle is related to the force stretching the spring by this mathematical relation
where x is the length by which the spring is stretched
Substituting the equation above for
making x the subject
Substituting the value
Answer:
the average force exerted on the ball by the bat is 11,613.27 N
Explanation:
Given;
mass of the baseball, m = 151 g = 0.151 kg
initial velocity of the baseball, u = 39.5 m/s
final velocity of the baseball, v = 45.1 m/s
time of action, t = 1.10 ms = 1.10 x 10⁻³ s
The average force exerted on the ball by the bat is calculate as;
Therefore, the average force exerted on the ball by the bat is 11,613.27 N
