WebThinking about velocity, speed, and definite integrals. Say a particle moves in a straight line with velocity v (t)=5-t v(t) = 5−t meters per second, where t t is time in seconds. When the velocity is positive it means the particle is moving forward along the line, and when the velocity is negative it means the particle is moving backwards. WebBefore the object reaches the maximum height, the vertical speed v y v_y v y v, start subscript, y, end subscript of a projectile decreases, because acceleration is in the opposite direction. The direction of the velocity is initially upward, since the object’s height is increasing (see Figure 3 below). WebWhere is the wind speed and is the object speed (both relative to ground).
