There’s force of friction/ drag that slows down a moving object, there’s also gravity pulling the wagon down which would help slow it down. Hope this helps good luck.

There actually three assertions here: one in A and two more in B.

All three assertions, as well as the reasoning described in this mess, are all False.

The correct choice from the list is e), but that doesn't even describe the complete Falseness of this disaster.

A small 21 kilogram canoe is floating downriver at a speed of 1 m/s. What is the canoe's kinetic energy?

tamaranim1 [39]

Kinetic energy is the energy of a moving object.
Kinetic energy can be calculated using the following equation;
K.E = $\frac{1}{2} m v^{2}$
where - m - mass of object
v - speed of object
substituting the values in the equation
K.E = 1/2 x 21 kg x (1 m/s)²
K.E = 10.5 J

Kevin has a mass of 87 kg and is skating with in-line skates. He sees his 22-kg younger brother up ahead standing on the sidewal

neonofarm [45]

Answer:

$V_ k = 3 m/s$

Explanation:

Using the conservation of the linear momentum P:

$P_i = P_f$

so:

$M_kV_k = M_sV_s$

where $M_k$ is the mass of kevin, $V_k$ is the velocity of kevin before he grabs her brother, $M_s$ is the velocity of her brother and him after grabs her brother and $V_s$ is the velocity of both after the collition.
