Answer:
(a).The value of force applied on the car during acceleration F = 383.32 N
(b).The value of impulse on the car I = 340.4 N-sec
Explanation:
Acceleration of the car [tex]a = \frac{4.6}{0.888}[/tex] = 5.18 [tex]\frac{m}{s^{2} }[/tex]
Mass of the passengers = 74 kg
Total force experienced by the car = mass × acceleration
⇒ F = m × a
Put the values of mass & acceleration in the above formula we get
Force F = 74 × 5.18
⇒ F = 383.32 N
This is the value of force applied on the car during acceleration.
linear Impulse is given by I = F × Δt
Where F = force applied on the car
Δt = time interval upon which the force is applied on the car
⇒ I = 383.32 × 0.888
⇒ I = 340.4 N-sec
This is the value of impulse on the car.
