Speed given in a instant
WebThe angular acceleration is given as α = −300rad/s2. Examining the available equations, we see all quantities but t are known in ωf = ω0 + αt, making it easiest to use this equation. Solution The equation states ωf = ω0 + αt. We solve the equation algebraically for t and then substitute the known values as usual, yielding WebSep 12, 2024 · Instantaneous speed = v(t) . If a particle is moving along the x-axis at +7.0 m/s and another particle is moving along the same axis at −7.0 m/s, they have different velocities, but both have the same speed of 7.0 m/s. Some typical speeds are shown in the following table. Calculating Instantaneous Velocity
