Why is horizontal acceleration 0 for projectile motion?
The horizontal acceleration is zero for projectile motion because there is no force acting on the projectile that would produce any acceleration in the horizontal direction. Acceleration is the result of a net force acting on an object.
If someone is moving away from you at 1 meter per second, the distance away from you changes by one meter every second. If the velocity is constant, then the second derivative will be zero. A ball thrown into the air will experience a constant acceleration in the downward direction.
What is the acceleration of a horizontal motion in a projectile motion?
The numerical information in both the diagram and the table above illustrate identical points – a projectile has a vertical acceleration of 9.8 m/s/s, downward and no horizontal acceleration. This is to say that the vertical velocity changes by 9.8 m/s each second and the horizontal velocity never changes.
What is the acceleration of a ball rolling across the floor?
A ball rolls across a floor with an acceleration of 0.100 m/s^2 in a direction opposite to its velocity. The ball has a velocity of 4.00 m/s after rolling a distance 6.00 m across the floor. What was the initial speed of the ball?
What is the initial velocity of the ball when it falls?
A ball is projected upward at time t = 0.0 s, from a point on a roof 90 m above the ground. The ball rises, then falls and strikes the ground. The initial velocity of the ball is 36.2 m/s if air resistance is negligible. The time when the ball strikes the ground is closest to
What is the formula for velocity as a function of time?
The velocity of an object as a function of time is given by v (t) = 2.00 m/s + (3.00 m/s) t – (1.0 m/s^2) t^2. Determine the instantaneous acceleration of the object at time t = 5.00 s.
What is the acceleration when a ball is dropped from a bridge?
The acceleration is downward during the entire time the ball is in the air. Two objects are dropped from a bridge, an interval of 1.0 s apart, and experience no appreciable air resistance. As time progresses, the difference in their speeds: Remains constant
