Answer: 94 seconds
Explanation:
An exact solution will require calculus, since the acceleration is not constant.
M*dV/dt = -fk = -75V
dV/V = -(75/M)dt
Since you have separated variables to opposite sides, the differential equation is easily integrated.
Therefore,
V2/V1 = -ln2 = (-75/M)T
where T is the time interval.
Then we have that,
T= (M/75)*ln2 = (1020/75)*0.693
= 94 seconds
The displacement of an object is obtained by taking out the area of the rectangle plus the area of the triangle under the line.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Suppose the initial position of an object is zero, the starting velocity is 3 m/s and the final velocity was 10 m/s. The object moves with constant acceleration.
In velocity time graph, the slope determines the acceleration and the area under the curve gives the value for the displacement.
Thus, the displacement of an object is obtained by taking out the area of the rectangle plus the area of the triangle under the line.

Answer: There is not work done at the door because the door did not move.
Explanation: Work is defined as the movement done by a force.
So if you move to apply a force F in an object and you move it a distance D, the work applied on the object is
W = F*D
In this case, the secret agent pushes against the door, so there is a force, but the agent does not move the door, so D = 0, so there is no motion of the door, which implies that there is no work done at the door.
