An automobile with initial speed 4 point 15 m per s accelerates uniformly at 2 point 7 m per s 2 and after 4 point 8 s the final speed is 17 point 11 m per s what is the displacement after 4 point 8 s?

Since the car accelerates uniformly, its average speed during the interval is
1/2 (initial speed + final speed) = 1/2 (4.15 + 17.11) = 10.63 m/s.
The distance covered is (average speed) x (time) = (10.63) x (4.8) = 51.024 meters.
If the motion during the 4.8 seconds was all in the same direction along a straight line,
then that same 51.024 meters is also the displacement during that time.
If, instead, it happened to take 4.8 seconds to go around a circle with a circumference
of 51.024 m, then the displacement over the 4.8 seconds is zero, since the starting line
is also the finish line.

How do you determine initial velocity when given time acceleration and displacement?
s = u + at s = displacement u = initial velocity a = acceleration t = time rearrange to give u = s - at and sub in values
How does the total time changes as the total distance increases in case of uniformly accelerated motio n?
the formula that ties displacement (you can think of it as distance in a given direction), velocity, time and acceleration (a) is : s = s0+vt + 1/2at^2 s0 = initial displacement (you can equate to 0, if you start at 0) vt = starting velocity times time (you can equate to 0 if initial velocity is 0) s= final displacement so s=1/2at^2 = (1/2 x a x t x t), so here you end up with a relationship between displacement, acceleration and time. (note: ^2 stands for "to the 2nd power")
What is the formula for calculating displacement in which initial velocity and time are the variables?
If the velocity is constant, thenDisplacement = (initial velocity) multiplied by (time)
What affects a pendulum?
The mass of the pendulum, the length of string, and the initial displacement from the rest position.
True or false To calculate the acceleration of and automobile you must first subtract the final speed from the initial speed?
True
How do you find the final and initial position of an object how would you calculate displacement?
To find the final position of an object, add the initial position and displacement. To calculate displacement, subtract the initial position from the final position. Mathematically, displacement = final position - initial position.
How do you find displacement when you only have acceleration initial velocity and final velocity?
You can use the equation: Displacement = (final velocity squared - initial velocity squared) / (2 * acceleration). Plug in the values of final velocity, initial velocity, and acceleration to calculate the displacement.
What is the formula for calculating displacement in which acceleration initial velocity and time are the variables?
If s = displacement, u = initial velocity, a = acceleration, t = time. Then s = ut + 1/2at2 Be careful to keep units consistent
What does displacement consist of?
Displacement refers to the change in position of an object from its initial position to its final position. It is a vector quantity that includes both magnitude (distance) and direction. Displacement can be calculated using the formula: displacement = final position - initial position.
How to find displacement?
Displacement can be found by calculating the difference between the final position and the initial position of an object. It is a vector quantity that includes both magnitude (distance) and direction. It can be determined using the formula: Displacement = Final position - Initial position.
How do you derive lateral displacement?
Lateral displacement can be derived using the formula: lateral displacement = initial velocity * time + 0.5 * acceleration * time^2. This formula takes into account the initial velocity, acceleration, and time taken for the object to undergo lateral displacement.
What is the name of the length of the straight line that is drawn form an objects initial position and to the object's final position?
Displacement
What is the displacement rule?
The displacement rule states that an object's displacement is the difference between its final position and its initial position. It can be calculated by subtracting the initial position vector from the final position vector. Displacement is a vector quantity that describes both the distance and direction of an object's movement.
How do you find a displacement?
Displacement can be calculated by subtracting the initial position from the final position of an object. It is a vector quantity that represents the change in position of an object in a specific direction. The formula for displacement is: Δx = x(final) - x(initial).
Does displacement of a particle depend on the actual path along which the particle move between two points?
No. Displacement is just the final location minus the initial location, regardless of the path.
Why is displacement of displacement?
Displacement refers to the change in an object's position from one point to another. It helps determine the object's overall movement in a specific direction. Calculating displacement gives a clear understanding of the object's final position in relation to its initial position.
What are properties of displacement?
Displacement is a vector quantity that describes the change in position of an object. It has both magnitude (length of the shortest path between the initial and final positions) and direction. Displacement is independent of the path taken, only dependent on the initial and final positions.
