a cricket ball is projected vertically upward direction.what kind of acceleration is acting on it
Chat with our AI personalities
When a cricket ball is projected vertically upward, the acceleration acting on the ball is gravitational acceleration directed downward. This causes the ball to slow down until it reaches the highest point of its trajectory, then it accelerates back downward due to gravity.
The direction of acceleration would be vertically upward, since the net force is acting in that direction. The horizontal motion of the balloon being blown westward does not affect the acceleration in the vertical direction.
The speed of the body at the highest point is 0 m/s. The acceleration acting on the body is the acceleration due to gravity (-9.81 m/s^2), which acts downward throughout the motion.
The horizontal acceleration of a ball rolling off a cliff is typically considered to be zero, assuming air resistance is neglected. The force of gravity acting vertically downward does not contribute to horizontal acceleration, as the ball falls vertically due to gravity while maintaining its initial horizontal velocity.
The acceleration of the sepaktakraw ball after 1 second will be approximately 9.81 m/s^2, assuming the ball is under the influence of gravity. This is the acceleration due to gravity acting downwards on the ball.
The two forces that cause an increase in normal force are the force of gravity acting vertically downwards and an additional force acting vertically upwards. When these forces increase in magnitude, the normal force provided by a supporting surface also increases to counteract them and maintain equilibrium.
