How does the mass of a wheelchair influence the force needed to move it?
Answer:
When mass is greater, the force needed must be greater keeping the acceleration of the wheel chair constant
Explanation:
[tex]force = mass \times acceleration \\ f \: \alpha \: m[/tex]
force is directly proportional to the mass
What causes you to miss an object you reach for when looking at it at an angle through two media?
A. The eyes get confusing signals because they are interpreting information from two different places.
B. The brain gets confusing signals because it is used to interpreting light that moves through air.
C. The hands get confusing signals from the eyes because of the change in medium.
Answer: A. The eyes get confusing signals because they are interpreting information from two different places.
Step-By-Step Explanation: I know this is right because it has happened to me, and others multiple times.

A car is moving at 80km/h accelerates to pass a truck. Five seconds later the car is moving at 100km/h. What is the Acceleration of the car? Please show the equation, Ty.
Answer/Explanation:
Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. Calculation of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. We can just use the kinematic equations. Fortunately, we are given these values. So, we calculate as follows:
acceleration = v - v0 / t
acceleration = (80 mph - 50 mph) ( 1 h / 3600) / 5 s
acceleration = 1.67 x 10^-3 m / s^2
An object of mass 100kg is moving with a velocity of 5m/s. Calculate the kinetic energy of that object
Answer:
1250 J
Explanation:
KE = 1/2(100 kg)(5 m/s)^2
KE = 1250 J

Which spring has more potential energy stored?
a) 1.0 N/m constant spring stretched 0.2 m.
b) 2.0 N/m constant spring stretched 0.2 m.
c) 1.0 N/m constant spring stretched 0.3 m.
d) 2.0 N/m constant spring stretched 0.3 m.
Work is done when spring is extended or compressed. Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.
Answer: c) 1.0 N/m constant spring stretched 0.3 m.

Answer:
A) y = 1.3x + 10
Explanation:
2 Points on the graph by using x and y values:
(0, 10) and (10, 23)
Slope:
m= (y2-y1)/(x2-x1)
m= (23 - 10)/(10 - 0)
m= 13/10
m = 1.3
Slope-intercept:
y - y1 = m(x - x1)
y - 10 = 1.3(x - 0)
y - 10 = 1.3x
y = 1.3x + 10
