Answer:
337.5m
Explanation:
<u>Kinematics</u>
Under constant acceleration, the kinematic equation holds:
, where "s" is the position at time "t", "a" is the constant acceleration, "
" is the initial velocity, and 
is the initial position.
<u>Defining Displacement</u>
Displacement is the difference in positions: 
or 
<u>Using known information</u>
Given that the initial velocity is zero ("skier stands at rest"), and zero times anything is zero, and zero plus anything remains unchanged, the equation simplifies further to the following:
So, to find the displacement after 15 seconds, with a constant acceleration of 3.0 m/s², substitute the known values, and simplify:
![\Delta s=\frac{1}{2}(3.0[\frac{m}{s^2}])(15.0[s])^2](https://tex.z-dn.net/?f=%5CDelta%20s%3D%5Cfrac%7B1%7D%7B2%7D%283.0%5B%5Cfrac%7Bm%7D%7Bs%5E2%7D%5D%29%2815.0%5Bs%5D%29%5E2)
![\Delta s=337.5[m]](https://tex.z-dn.net/?f=%5CDelta%20s%3D337.5%5Bm%5D)
Answer: Weight truck+load = 29.4×
N
Explanation: When an object floats in a fluid, there is an upward force, caused by the liquid, acting on the object that opposes the weight of the immersed object. This force is called <u>Buyoyant</u> <u>Force</u> and is determined by:
B = d*V*g
where
d is density of the fluid;
V is volume of liquid displaced due to the immersed object;
g is acceleration due to gravity;
For the truck, the system is in equilibrium, which means buyoyant force is equal weight. Then:
Volume displaced is
V = 10*8*0.0375
V = 3 
Density of water: 1000kg/
= 1000*3*9.8
= 29.4× N
The weight of the truck and the load is 29.4× Newtons
