Question

A stone of mass 4.0kg is pulled along a horizontal path by a rope which makes an angle of 30 with the horizontal. Neglecting friction, calculate the tension in the rope if the body accelerates uniformly at 2m/s2​

Answer 1

9.24 N

Step-by-step explanation:

The force accelerating the 4 kg body is the horizontal force = T cos 30

F= ma so:

T cos 30 = 4 kg ( 2 m/s^2)

T = 8 / cos (30) = 9.24 N
