Auniform sphere of mass 3.5 kg and radius 0.4 m rolls down a ramp inclined at an angle 0.2 radians to the horizontal. what is the acceleration of the rolling sphere in m/s^2.

1.4 m/s²

Explanation:

m = mass of the uniform sphere = 3.5 kg

r = radius of the sphere = 0.4 m

θ = angle of the incline = 0.2 rad = 11.5 deg

g = acceleration due to gravity = 9.8 m/s²

a = acceleration of the rolling sphere

acceleration of the rolling sphere is given as

a = g Sinθ

Inserting the values

a = (9.8) Sin11.5

a = 1.4 m/s²

your answer is c! hope this : )

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
