Usama Adeel – StudySmarter Originalsĭistance traveled in the x-direction: d x = ?Īcceleration due to free fall = a y = -9.81 m/s 2įrom the motion in the y-direction, we can calculate the time t because time is the same in the x and y-direction. The velocity in the x-direction will stay constant. The velocity in the y-direction will increase because of the acceleration in the y-direction. The displacement horizontally will be -30m because the downward direction is considered negative along with the acceleration of free fall, which is -9.81 m/s 2.įigure 4. Hence, the ball rolls off the cliff with an initial velocity of 0m/s in the y-direction. In the y-direction, the ball has a constant acceleration of 9.81m/s 2, which is caused by the gravitational force.īut what’s the initial velocity in the y-direction?Īs mentioned previously, because the motion in both x and y directions are independent of each other, the 5m/s velocity in the x-direction has no impact on the movement in the y-direction. To calculate d, the distance from the base of the cliff, we need to understand more about the motion in x and y directions.Īssuming there is no air resistance and just the gravitational force acting on the ball, the speed in the x-direction will be 5m/s until the ball hits the ground. Calculate the range d covered by the object.įigure 3. Figure 3 shows the projectile motion without an angle, i.e. The body hits the ground at a distance d away from the base of a cliff that has a height of 30 m. Suppose you have a body that rolls off a cliff with a velocity of 5 m/s.
