A 0.5kg baseball experiences a 10N force for a duration of 0.1s. What is the change in velocity of the baseball

Respuesta :

Force • time = mass • (final velocity - initial velocity)
10 x 0.1 = 0.5 • change in velocity
answer= 0.2

An attribute that can change the state of motion of an object is called force. It can alter the velocity or the acceleration of a moving particle. Force is estimated in Newton.

The change in velocity of the baseball is 2 m/s.

Force is calculated by:

[tex]\rm I = F \times t[/tex]    (equation 1)

Where, I = impulse, F = force and t = time

Also,

[tex]\rm I = m \Delta v[/tex]     (equation 2)

Therefore, from equation 1 and 2:

[tex]\rm F \times t = m \Delta v[/tex]

Given,

  • F = 10N
  • t = 0.1 sec
  • m = 0.5 kg

Substituting values in the equation:

[tex]\begin{aligned}\rm \Delta v &= \rm \dfrac{F \times t}{m}\\\\&= \dfrac{10 \times 0.1 }{0.5}\\\\&= 2\;\rm m/s\end{aligned}[/tex]

Thus, 2m/s is the change in the velocity due to impulse.
