Sagot :
The final velocity of the body is 2.675 m/s.
To find the final velocity of the body, we use the formula below.
Velocity
This can be defined as the ratio of displacement to time. the S.I unit of velocity is m/s.
⇒ Formula:
- F = m(v-u)/t.................... Equation 1
⇒ Where:
- F = Force
- m = mass of the body
- v = final velocity
- u = initial velocity
- t = time.
⇒ make v the subject of the equation
- v = (Ft/m)+u.................. Equation 2
From the question,
⇒ Given:
- F = 15 N
- m = 20 kg
- u = 0.5 m/s
- t = 2.9 s
⇒ Substitute these values into equation 2
- v = [(15×2.9)/20]+0.5
- v = 2.675 m/s
Hence, the final velocity of the body is 2.675 m/s.
