What height will it reach in 1 second if a = -10 m/s²? Ignore air resistance in your calculation. \ Higher - Combining these two equations givesĪ toy rocket is fired vertically upwards against gravity with an initial velocity of 20 m/s. Calculate its final velocity, ignoring air resistance. To do this, simplify the equation to find v:Ī biscuit is dropped 300 m, from rest, from the Eiffel tower. The distance traveled is measured with any convenient point on the pulse. The equation above can be used to calculate the final velocity of an object if its initial velocity, acceleration and displacement are known. The initial velocity (vi) is the velocity of the object before a change due to acceleration. The velocity-position equation of an object that is moving in a straight line is v2-164x. The velocity is constant and the pulse moves a distance x vt in a time t. The equation can also be used to calculate the acceleration of an object if its initial and final velocities, and the displacement are known.
