In projectile motion we can say initial components of velocity is
now here horizontal motion is uniform motion as there is no force in this direction while in vertical direction due to gravity it will accelerate
so we have
so here we have x and y coordinates are related to each other as it will take same time to move the positions
so here correct options are
<em>Projectile motion is a combination of horizontal and vertical motion. </em>
<em>The horizontal and vertical motions of a projectile are dependent on each other.</em>
Answer:
15.38 m.
Explanation:
The kinetic energy of the block is equal to potential energy of spring at maximum compression
1/ 2 m V² = 1 /2 K X²
m is mass of block , V is its velocity , K is spring constant and X is maximum compression or its amplitude.
X =
Putting the values
x =
= 15.38 m.
