5. a box weighs 196 n. a rope is tied to the box. what is the
tension in the rope if
(a) the box is accelerating upwards at 5 m/s? :
what is the tension in the rope?

296 N

Explanation:

Draw a free body diagram.  The box has two forces on it: tension up and weight down.

Apply Newton's second law:

∑F = ma

T − mg = ma

T = m (g + a)

Given m = 196 N / 9.8 m/s² = 20 kg, and a = +5 m/s²:

T = (20 kg) (9.8 m/s² + 5 m/s²)

T = 296 N

true tan speed = ang vel x radius

probably not if net force is zero
