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
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
The acceleration due to gravity on planet Alpha is B) 8.0 m/s2
Explanation:
The weight of a body is given by:
where
m is the mass of the body
g is the acceleration of gravity at the location of the body
In this problem, we have:
m = 70 kg is the mass of the astronaut
W = 560 N is the weight of the astronaut on the surface of planet Alpha
Therefore, we can re-arrange the equation to find g, the acceleration of gravity on the planet:

Answer:
a = - 3.14[m/s^2]
Explanation:
To solve this problem we must use the following kinematic equation:
Now replacing:
The negative sign means the vehicle slows down.
Answer:
so your doing the experiment and no one knows what the experiment is but if your just wontdering what a independent variable and dependent variable is then > > >
Explanation:Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences
for example a plant assigment.
