Question

The variation of speed of a train (consisting of an engine and 10 identical passenger coaches each of mass $3 \times 1 0^{3} kg$ ) with respect to time is as given below. Find the tension in the coupling link connecting engine and the first coach at $t = 1$ sec .

Options:

Answer:

C

Solution:

$at t = 1 sec a = 2 m / s^{2} T = N (ma) = 10 (3 \times 1 0^{3}) (+ 2) = + 60 \times 1 0^{3} N$
