A 0.144 kg baseball is moving towards home plate with a speed of 43.0 m/s when it is bunted. the bat exerts an average force of

Ganezh [65]

As per impulse momentum theorem we know that

$F\Delta t = m(v_f - v_i)$

now here we will have

$F = 6.50 \times 10^3 N$

t = 1.30 ms

m = 0.144 kg

$v_i = -43 m/s$

now we need to find final speed using above formula

$(6.50 \times 10^3)(1.30 \times 10^{-3}) = 0.144 ( v_f - (-43))$

$v_f = 15.7 m/s$

so final speed is given as above

Describe the change that occurs in the pattern of atmospheric temperature at the pauses

MAVERICK [17]

Within each layer temperature either goes up (in the stratosphere and thermosphere) or down (in the troposphere and mesosphere). Boundaries "pauses<span>" between layers are defined by where temperature stays about the same with height.

Hope this helps!
