The object is moving with constant speed means there is no change in speed Hence the acceleration is 0
Where, u is initial speed,
v is final speed
t is time taken and
a is acceleration
a = ( v-u) /t
a =(0)/t because u=v
a=0
Therefore, Acceleration is 0
Answer:
As rocket mass increases, acceleration decreases.
Explanation:
From Newton's second law of motion;
F= ma
Where;
m= mass of the object
a= acceleration of the object
Hence we can write;
a= F/m
This implies that an increase in mass (m) will lead to a decrease in acceleration if the force on the object is held constant.
Hence, if the rockets have different masses, they will have different accelerations.
Answer:
h = 20 m
Explanation:
height (h) = 10 m
potential energy (PE) = 50 J
kinetic energy (KE) = 50 J
what is the maximum height reached by the ball
- At 10 meters above the ground potential energy (PE) = 50 J
mgh = 50
recall that height (h) = 10
mg (10) = 50
mg = 5 .....equation 1
- The total energy of the system at 10 meters is given as PE + KE = 100 Joules. From the conservation of energy the total energy in the system still remains the same at the maximum height, this is because energy can neither be created nor destroyed but can be transformed from one form to another.
- At the maximum height the velocity (v) of the system is 0, which means all its kinetic energy (KE) is converted to potential energy. Therefore the system consist only of potential energy.
KE + PE = 100
+ mgh = 100 J
velocity (v) = 0 at maximum height therefore
0 + mgh = 100
mgh = 100
recall that mg = 5 from equation 1, therefore
5h = 100
h = 20 m
After evaluating the equation, you should get a numerical value for the slope of the line such as slope, m = 1.13.
<h3>What is a graph?</h3>
A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
<h3>How to calculate the slope of a line?</h3>
Mathematically, the slope of a line can be calculated by using this formula;
Next, you should read the points on the x-axis and y-axis of your graph and then substitute them into formula for calculating the slope of a line.
After evaluating the equation, you should get a numerical value for the slope of the line such as slope, m = 1.13.
