Answer:
0.73 m/s in the forward direction
Explanation:
The caterpillar's velocity relative to the ground is given by:
where
is the velocity of the wagon with respect to the ground
v is the velocity of the caterpillar in the wagon's reference frame
In this situation we have
where the negative sign is due to the fact that the caterpillar is moving backward
Substituting,
The formula for getting the distance will be distance = speed x time
D = S x T
speed or velocity = 50km/h
time = 0.5 h
the equation will be done directly because it's already in it's SI units
distance = 50km/h x 0.5h
hour cancels hour and the equation remains = 50km x 0.5
Ans = 25 km
the train will move 25 km far in 0.5h
All you do is 0.5 times the mass times the kenetic energy hope this helps
