A worker develops a tension T in the cable as he attempts to move the 50−kg cart up the 21∘ incline. Determine the resulting acceleration a of the cart if (a) T = 129 N and (b) T = 206 N. Neglect all friction, except that at the worker's feet. The acceleration a is positive if up the slope, negative if down the slope. Answers: (a) T = 129 N, a = m/s2 (b) T = 206 N, a = m/s2

A worker develops a tension

T

in the cable as he attempts to move the

50 - k g

cart up the

21^{\circ}

incline. Determine the resulting acceleration

a

of the cart if (a)

T = 129 N

and (b)

T = 206 N

. Neglect all friction, except that at the worker's feet. The acceleration

a

is positive if up the slope, negative if down the slope.

Answers: (a)

T = 129 N, a =

◻

m / s^{2}

(b)

T = 206 N, a =

◻

m / s^{2}
