What is instantaneous acceleration?

2 answers:

7 0

Explanation:

Instantaneous acceleration is the acceleration at a particular instant. Mathematically, it is the first derivative of velocity, dv/dt.

Average acceleration, on the other hand, is the acceleration over a period of time. It is the change in velocity divided by the length of time, Δv/Δt.

A pitcher throws a 0.14-kg baseball toward the batter so that it crosses home plate horizontally and has a speed of 42 m/s just

kykrilka [37]

Answer

given,

mass of base ball = 0.14 kg

speed before it made the contact with the ball (V i) = 42 m/s

speed after batter hit the ball(V f) = - 48 m/s

impulse = change in momentum

= $m\times (V_f-V_i)$

= $0.14\times (-48-42)$

= -12.6 Kg m/s

Magnitude of impulse = 12.6 Kg m/s

Force = $\dfrac{impulse}{time}$

= $\dfrac{12.6}{0.005}$

Force = 2520 N
