v2 - u2 = 2as
so that a = (v2 - u2)/2s
where
u = initial velocity
v = final velocity
s = distance
a = acceleration
Assuming constant acceleration: distance = v(0) t + (1/2) a t squared Where v(0) is the initial velocity.
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.
You use the information you're given, along with the equations and formulas you know that relate distance, time, speed, and acceleration, to calculate the number you're asked to find. And here's a tip: Chances are that the initial acceleration, the final acceleration, and the acceleration all along the way, are all the same number.
To find the distance traveled by an object with a given acceleration and initial velocity, you can use the formula: distance (initial velocity time) (0.5 acceleration time2). This formula takes into account the initial velocity, acceleration, and time the object has been moving to calculate the total distance traveled.
To find the acceleration of an object moving in a straight line, you must calculate the change in velocity during a unit of time. Acceleration is the rate of change of velocity over time, not distance. It is given by the formula acceleration = (final velocity - initial velocity) / time.
Assuming constant acceleration: distance = v(0) t + (1/2) a t squared Where v(0) is the initial velocity.
To find the velocity when given the acceleration and time, you can use the formula: velocity acceleration x time. Simply multiply the acceleration by the time to calculate the velocity.
To find the acceleration of an object, you can use the formula: acceleration change in velocity / time taken. If you have the distance and time measurements, you can calculate the velocity by dividing the distance by the time. Then, you can find the change in velocity by subtracting the initial velocity from the final velocity. Finally, divide the change in velocity by the time taken to find the acceleration.

To find the magnitude of acceleration in a given scenario, you can use the formula: acceleration change in velocity / time taken. Calculate the difference in velocity between two points and divide it by the time taken to travel that distance. The result will give you the magnitude of acceleration.
To find the final velocity when given the acceleration and time, you can use the formula: final velocity initial velocity (acceleration x time). Simply plug in the values for acceleration and time, and calculate the final velocity.
To find acceleration when given distance and time, you can use the formula: acceleration 2 (distance / time2). Simply divide the distance by the square of the time to calculate the acceleration.
To find the magnitude of acceleration in a scenario, you can use the formula: acceleration change in velocity / time taken. Calculate the difference in velocity between two points and divide it by the time taken to travel that distance. The result will give you the magnitude of acceleration.
If the acceleration of the car is given, you can calculate the change in velocity using the formula: final velocity = initial velocity + (acceleration * time). You need to know the initial velocity and the time for which the acceleration is acting to determine the final velocity.
To calculate stopping distance, we need to first find the deceleration of the car using the formula: force = mass x acceleration. Given that force = -3000 N and mass = kg, we can find the acceleration. Once the acceleration is known, we can use the equation of motion: final velocity^2 = initial velocity^2 + 2 x acceleration x distance to calculate the stopping distance.
