Answer:
Friction = 5.027 N
Explanation:
Kinetic friction does not change with speed or acceleration. The only thing that is required is to state that the object is moving.
Solving the force equation for friction we get:
Friction = coefficient of friction* normal force exerted by the object
Friction = u * R
here R is = 0.84 * Gravity = 0.84 * 9.81 = 8.2404 N
u = 0.61 (as stated in the question)
So frictional force will be:
Friction = 0.61 * 8.2404
Friction = 5.027 N

Explanation:
Data
Duane Albert
d = 5 m ; v = 3 m/s v = 4.2 m/s
a) b)
Duane's Albert's
d = 5 + (3)t d = 4.2t
d = 5 + 3t
c) 5 + 3t = 4.2t
4.2t - 3t = 5
1.2t = 5
t = 4.17 s
d)
Duane's
d= 5 + 3(4.17)
d = 17.51 m
Alberts
d = 4.2(4.17)
d = 17.51 m
Given that,
A whale dives at an angle of 24 degrees to the horizontal surface of the water.
The whale continues in a straight line 145 m.
To find,
The horizontal and vertical components of the displacement of the whale.
Solution,
The horizontal component of displacement is :
The vertical component of displacement is :
<h3>Hence, the horizontal and vertical components of the displacement of the whale are 132.46 m and 58.97 m.</h3>
Density = Mass / Volume
Volume = Area x Length = (4.50 x 5.20) x 6.00 = 140.4
Density = 1587 x 140.4 = 222,814.8 g/cm3 (cubed)
222,814.8 / 1000 = 222.8148 kg/m3 (cubed)
