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

- measure reactants precisely. ( first choice)

- stir to the reaction take place. ( second choice)

- wait patiently until the reaction completes. ( fourth choice)

- make sure to recover as much copper as possible. ( last choice)
