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 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.

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.
To find the acceleration if the time is not given, you will need to know the velocity and the distance. Then, use this equation: d = vt + (1/2)at2 to solve the problem by plugging in your numbers for the distance and the velocity.
Speed and time. As acceleration is the change in speed over time.However, if you do not have a direct reading of speed, you will need to claculate that also, from distance over time.So all the units are:-Distance = MetresTime. = SecondsSpeed = m/sAcceleration = m/s/s or m/s2
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
yes...
You can calculate displacement using the equation: displacement = initial velocity x time + 0.5 x acceleration x time^2. Given the initial velocity, time, and acceleration, you can find the displacement even if the final velocity is not given.
Without time given, it is not possible to calculate the initial speed. The initial speed can be determined only if you have the time taken to reach a certain point from rest, along with the distance traveled or acceleration information. The formula to calculate initial speed is v = u + at, where v is the final velocity, u is the initial velocity, a is acceleration, and t is time.
Distance traveled can be calculated using the formula: distance = 0.5 * acceleration * time^2, where acceleration = force / mass. First, calculate acceleration by dividing the force by the mass, then plug the acceleration value into the formula along with the time to find the distance traveled.
