When the mass of the cart changes, the time to travel at 4.6 m/s is 28.11 s.
Acceleration of the mule
The acceleration of mule is calculated as follows;
a = v/t
a = 5/10
a = 0.5 m/s²
For constant applied force
F1 = F2
m₁v₁/t₁ = m₂v₂/t₂
(180 x 5) / 10 = (550 x 4.6)/t
90 = 2530/t
t = 2530/90
t = 28.11 s
Thus, when the mass of the cart changes, the time to travel at 4.6 m/s is 28.11 s.
