The body moves along the OX axis at a constant speed of 4m / s, and along the OY axis with an initial zero speed and a constant acceleration equal to 1.5m / s, determine the body’s speed in 2 seconds after the start of movement along the OY axis.
The speed along the OY axis will be equal to U = at = 1.5 * 2 = 3m / s. The projection of the speed OX will not affect the projection of the speed onto OY, since these speeds are perpendicular.
