WebAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense. WebThis equation applies to objects in uniform acceleration: (final velocity)2 – (initial velocity)2 = 2 × acceleration × distance \ [v^ {2} – u^ {2} = 2αx\] This is when: final velocity (v) is...

WebThe third kinematics equation gives the final speed as: v_f^2 = 2 ( 9.8 \text { m}/\text {s}^2) (100 \text { m}) \implies v_f \approx 44.3 \text { m}/\text {s}. vf 2 = 2(9.8 m/s2)(100 m) vf ≈ 44.3 m/s. The first kinematical equation gives the time to accelerate up to this speed: 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:
