Answer:
T = 1633N
Explanation:
The weight of the man is given by m×g =112×9.8= 1097.6N
Coefficient of Kinetic Friction = frictional force / Normal reaction ( Weight of object)
The coefficient of Kinetic Friction= Tan A
Where A is the angle of inclination
The angle of inclination is Tan^-1{0.876} = 41.21°
By identity sin A = Opposite( weight)/ hypothenus ( Tension)
Hence the tension is T = 1097.6/sin 41.21 =
T = 1633N
Answer:
Acceleration due to gravity on a certain planet = 4 m/s²
Explanation:
According to the question,
Weight = 30 N
Mass = 7.5 kg
Let acceleration due to gravity be 'a'
<u>Formula</u>:
Weight = Mass × Acceleration due to gravity
30 = 7.5 × a
a = 30/7.5
a = 4 m/s²
