Chemical energy (calories) is converted by your body walking on the surface into mechanical/kinetic energy
Answer:
b racism bc saying whites are better than blacks is racist
5m/s
Explanation:
Given parameters:
Mass of ball = 0.1kg
Force on the ball = 5N
time taken = 0.1s
Unknown:
final speed of the ball = ?
Solution:
According to newton's second law "the net force on a body is the product of its mass and acceleration".
Force = mass x acceleration equation 1
Acceleration =
V is the final velocity
U is the initial velocity
T is the time taken
U = O since it is a stationary body;
a =
Input "a" into equation 1
F = m x
5 = 0.1 x
V = 5m/s

We have that the speed of the ice at the bottom is mathematically given as
v=1.8812m/s
<h3>The speed of the ice at the bottom </h3>
Question Parameters:
A 8.00 kg block of ice, released from rest
at the top of a 1.50-m-long frictionless ramp,
slides downhill, reaching a speed of 2.70 m/s
constant friction force of 10.0 N parallel to the surface of the ramp
Generally the equation for the Potential Energy is is mathematically given as
P.E=K.E+W_{fric}
Therefore
mgh=0.5mv^2+W_{fric}
Where
W_{fric}=F.S
W_{fric}=10*1.50
W_{fric}=15
And
mgh=0.5mv^2+
h=0.3719
Hence
0.5(8.00)(v^2)=(8.00)(9.8)(0.3719)-15
v^2=3.53924
v=1.8812m/s
