Why do you had to calculate acceleration with velocity?
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
How do you calculate acceleration when given velocity and distance?
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
How do you calculate power when given speed acceleration weight and distance?
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.
How do you find initial acceleration.?
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.
