Answer:
The acceleration is
Explanation:
From the question we are told that
The mass of the engine is
The mass of each Boxcar is
The tension between the locomotive and boxcar A is
Generally the tension between the locomotive and boxcar A is equivalent to the net force propelling the box cars so the tension is mathematically represented as
Here M is the mass of the three box cars

Answer:
u= 35.30 s
Explanation:
given,
horizontal distance covered by the ball = 105 m
vertical distance to clear by the ball = 4 m
angle at which the ball was hit = 31°
Let the initial velocity is u m/s and the ball take t sec to reach the fence.
ut = 122.5
Using
t = 3.47 s
now,
u= 35.30 s
Speed of the ball when it leaves the bat u= 35.30 s
