It describes how quickly or slowly an object moves from one place to another. The standard (SI) unit of speed is meters per second (m/s), but it can also be expressed in other units, such as kilometers per hour (km/h), miles per hour (mph), or feet per second (ft/s), depending on the context or the country's measurement system.
May 1, 2024 · Suppose that you have two velocity vectors with speeds v 1 = 3 m/s and v 2 = 6 m/s, and directions θ 1 = 30 deg and θ 2 = 60 deg. You can find the resultant velocity following the steps below: Calculate the v x res component using the equation: v x res = v 1 cos θ 1 + v 2 cos θ 2 ≈ 5.6 m/s. Determine the v y res component through the formula:

Oct 21, 2023 · distance = speed x time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time. distance = rate x time. To solve for speed or rate use the ...
Had there been no blockage, the bus would have traveled at x Km/h. Its travel time would have been: t usual = AB/x = 500/x hours. The bus reached town B on time, despite blockage, therefore: Usual time = Time to travel the distance AC + Delay + Time to travel the distance CB. t u s u a l = t A C + 2 1 + t CB x 500 = x 300 + 2 1 + x + 20 200
