Answer:
acceleration a = 3.67 m/s^2
Completed Question:
A block of mass 3 kg, which has an initialspeed of 6 m/s at timet= 0, slides on ahorizontal surface. If a constant friction force of magnitude 11 Newtons is exerted on the block by the surface, find the magnitude of the acceleration of the block. Answer in units of m/s 2
Step-by-step explanation:
Force = mass × acceleration
F = ma ........1
Given that;
Force F = 11 N
mass m = 3 kg
Acceleration a can be derived from equation 1
Making a the subject of formula;
a = F/m
Substituting the given values;
a = 11N/3kg
a = 3.66666... m/s^2
acceleration a = 3.67 m/s^2
