A particle is projected with a velocity v

This action cannot be undone. This will permanently delete All Practiced Questions. At any instant, its velocity v is at right angles to its initial velocity u; then v is:. A ship A is moving westwards with a speed of 10 km h - 1 and a ship B, km south of A is moving northwards with a speed of 10 km h - 1. The time after which the distance between them becomes the shortest, is:. Then the variation of kinetic K with vertical displacement y is. A swimmer wants to go to point 'C' starting from 'A'. A body is thrown horizontally with a velocity 2 g h from the top of a tower of height h. It strikes the level ground through the foot of the tower at a distance x from the tower. The value of x is:. The time when they will meet for the first time, is equal to: 1. Change in velocity after the time t from the time of projection will be:. Are you sure? Clear Question Attempted. Botany All.

A particle is projected with a velocity v

The learning objectives in this section will help your students master the following standards:. In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Motion in Two Dimensions, as well as the following standards:. Projectile motion is the motion of an object thrown projected into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. The object is called a projectile , and its path is called its trajectory. Air resistance is a frictional force that slows its motion and can significantly alter the trajectory of the motion. Due to the difficulty in calculation, only situations in which the deviation from projectile motion is negligible and air resistance can be ignored are considered in introductory physics. That approximation is often quite accurate.
