Question

5. A monkey of mass 50 Kg climbs up a rope. Find the tension experienced by the rope in
the following cases:
a) Climbs up with an acceleration of 5 m/s?
b) Climbs down with an acceleration of 5 m/s..
c) Climbs up with a uniform speed of 6 m/s. 3​

Answer 1

For climbing upward with acc. a

$T=m(a + g) - - (1)$

For climbing downward with acc. a

$T=m(g-a) - - (2)$

For climbing upward with uniform speed

$T=mg - - (3)$

(a)

By using eq. (1)

$T=50(10+5)$

$T=50 \times 15$

$T=750N$

(b)

By using eq. (2)

$T=50(10-5)$

$T=50 \times 5$

$T=250N$

(c)

By using eq. (3)

$T=50 \times 10$

$T=250N$
