Answer:
Depends on the specific relation of acceleration as function of time, but it would always look like decresing or increasing negatively.
Explanation:
Acceleration is the derivative of velocity with respect to time. That means that it is the change. The fact that is negative means that it is decreasing, or increasing in the negative direction (i.e. going backwards faster).
Attached is the graph with constant negative acceleration, using kinematics relations, it would be a linear equation with negative slope.
Answer:
Explanation:
The acceleration of an object is given by Newton's second law:
where
F is the net force applied on the object
m is the mass of the object
For the book in the problem, we have:
is the mass
is the force applied
Substituting into the formula, we find the acceleration:
Answer:
Final speed of boat + man is 1.66 m/s
Explanation:
As we know that there is no friction on the system or there is no external force on this system
So here we can use momentum conservation here
so we have
m = 85 kg
M = 135 kg
v = 4.30 m/s
now we have
