(a) The book decelerates as it moves upwards with magnitude of 6.77 m/s²
(b) The distance traveled by the book before stopping is 0.36 m.
The given parameters;
- mass of the book, m = 1.23 kg
- mass of coffee cup, m₁ = 505 g = 0.505 kg
- initial velocity, u = 2.21 m/s
- coefficient of kinetic friction, μk = 0.221
The vertical component of the force on the book-cup system;
The frictional force on the system;
The horizontal component of the force on the system;
The acceleration of the book along the slope is calculated as;
Thus, the book decelerates as it moves upwards with magnitude of 6.77 m/s²
(b) The distance traveled by the book before it comes to stop is calculated as;
Thus, the distance traveled by the book before stopping is 0.36 m.

Hello. You forgot to put the image that shows information needed to answer that question. The image is attached below:
Answer:
The cuboid and the cube exert the same pressure on the floor.
Explanation:
To answer this question, we must first consider that the area of the cuboid is equal to 24cm^2, while the area of the cube is equal to 16cm^2.
With that, we must calculate the pressure that each exerts, with the formula:
P = F / A
Cuboid: P = 60 / 0.0024 = 25000 N/m^2
Cube: P = 40 / 0.0016 = 25000 N/m^2

By definition, the kinetic energy is given by:
Where,
m: mass of the object
v: object speed
Substituting values we have:
Doing the calculations we have
The energy unit is joules
Answer:
the canoe's kinetic energy is:
Explanation:
Inertia is the measure of the mass of an object. It is the tendency of an object to change the direction of an object.
Momentum is the product of mass and velocity. When an object having mass m moves with a particular velocity it will have momentum.
If the speed of an object is changed from u to v, its momentum can be changed and it can be calculated as :
Δp = m(v-u)
Hence, this is the required solution.
