Answer:
F = 11046 N
Explanation:
given,
mass of the baseball (m)= 145 g = 0.145 Kg
horizontal speed(u) = -36 m/s
ball hit is straight back(v) = 47.8 m/s
time of contact = ?
using formula of impulse
Impulse = change in momentum
I = m v - m u
I = 0.145 x (47.8 - (-36))
I = 0.145 x (83.8)
I = 12.151 kg.m/s
we also know
I = F x t
now,
F x t = 12.151 kg.m/s
F x 1.1 ms = 12.151
F = 11046 N
1.25m/s'2 by the first eq of motion
see the steps below
Individuals have different traits because they are not twins so they should not be alike also because people have different genes witch would give them different traits. For example not every individual has blonde hair and blue eyes because they did not inherit those traits.
