A 14-kg block rests on a level frictionless surface and is attached by a light string to a 5.0-kg hanging mass where the string passes over a massless frictionless pulley.If g = 9.8 m/s²,what is the tension in the connecting string? A)2.6 N B)21 N C)49 N D)36 N E)190 N

Question

Quizplus · Accepted Answer

The tension in the string can be found using the formula T = m2 * g / (m1 + m2), where m1 is the mass on the surface and m2 is the hanging mass. Substituting the given values, T = 5 * 9.8 / (14 + 5) = 36 N.
