Answer:
2.31m/s² downwards
Explanation:
The sum of forces on the object is expressed as;
T-W
T is the tension on the rope
W is the weight
According yo Newton's second law:
T-W= ma
m is the mass
a is the acceleration
Given
T = 75N
W = mg = 10×9.81
W = 98.1N
Substitute
75-98.1 = 10a
-23.1 = 10a
a = -23.1/10
a = -2.31m/s²
The magnitude of the acceleration is 2.31m/s² and directions is downwards
