WebYes, instead of multiplying by time you can just plug the numbers into the equation: time = distance / rate (speed). In this case it would be: time = 720m / 3m per sec When you divide 720m by 3m/s the meters cancels out and you are then left with time which would be 240 seconds. This equation though is just a manipulation of rate = distance/time. WebMar 21, 2024 · A sprinter can accelerate with constant acceleration for 3.40 s before reaching top speed. He can run the 100-meter dash in 10 s. What is his speed as he crosses the finish line?

WebThe formula is commonly rearranged as: \ [v = u + at\] to give the final speed \ (v\) of an object after it has accelerated. Acceleration is measured in metres per second per … Webpi = m1vi1. After the hit, the players tangle up and move with the same final velocity. Therefore, the final momentum, pf, must equal the combined mass of the two players multiplied by their final velocity, ( m1 + m2) vf, which gives you the following equation: ( m1 + m2) vf = m1vi1. Solving for vf gives you the equation for their final velocity:
WebFigure 4.12 (a) We analyze two-dimensional projectile motion by breaking it into two independent one-dimensional motions along the vertical and horizontal axes. (b) The horizontal motion is simple, because a x = 0 a x = 0 and v x v x is a constant. (c) The velocity in the vertical direction begins to decrease as the object rises. At its highest … WebDec 9, 2024 · average speed = total distance / total time. Typical units are kilometers per hour (kph), miles per hour (mph), meters per second (m/s) and feet per second (ft/s).
