Jack pulls eastward with a force of 98.7 N, Jill Three pulls with 86.9 N in the northeast direction, and Jane pulls to the southeast with 131 N. (Since the donke is involved with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude o the net force the people exert on the donkey. Number What is the direction of the net force? Express this as the angle from the east direction between 0 and 90° with a positive sign for north of east and a negative sign for south of east. Number

Explanation / Answer

Fjack = 98.7 i^

Fjill = (61.46 , 61.46 ) N (Assuming 45 degree angle)

F jane = (92.64 , -92.64 ) N (Assuming 45 degree angle)

Ft = (252.8, -31.18) N

Magnitude = 254.72 N (ans)

Direction = -7.03 degree (ans)
