A 0.10 kg baseball travelling at 40 m s−1 hits straight back to the pitcher at 55 m s−1. The contact time is 0.01 seconds. What is the change in momentum of the baseball? ​

Answer:

1.5 kgms⁻¹

Step-by-step explanation:

Momentum can be defined as "mass in motion."

The amount of momentum that an object has is dependent upon two factors

  • mass of the moving object
  • speed of motiom

when there is a change in the velocity , it creates a change in momentum also

when we consider that we can mathematically show this,In terms of an equation,

Change in momentum (ΔΡ) = m(Δv)

where (Δv) - change in velocity

(Δv) = final velocity - initial velocity

Change in momentum (ΔΡ) = m(Δv)

= 0.1×([55-40])

= 1.5 kgms⁻¹
