Answer:</h2>
Answer to this question is (A)
<h2>
Explanation</h2>
A ball bouncing on the floor is not the example of simple harmonic motion. SHM is the special kind of to and fro motion in which a particle oscillate about its mean position in a straight line. The acceleration of the particle is always directed towards its mean position and is directly proportional to its displacement from its mean position.
In case of a ball bouncing on the ground, the motion of the ball is not SHM, as neither it’s a to and fro motion nor the acceleration is proportional to its displacement from its mean position.
Answer:In non-uniform circular motion, an object's motion is along a circle, but the object's speed is not constant. In particular, the following will be true. The object's velocity vector is always tangent to the circle. The speed and angular speed of the object are not constant
Explanation:In non-uniform circular motion an object is moving in a circular path with a ... Since the speed is changing, there is tangential acceleration in ... Here is an example with an object traveling in a straight path
Answer:
Explanation:
Given
initial speed of Launch
=53.7 m/s
Range of Projectile =Maximum height of Projectile
Range is given by R
Maximum height is given by 
![\frac{u^2\sin \theta }{g}\cdot \left [ 2\cos \theta -\frac{1}{2}\right ]=0](https://tex.z-dn.net/?f=%5Cfrac%7Bu%5E2%5Csin%20%5Ctheta%20%7D%7Bg%7D%5Ccdot%20%5Cleft%20%5B%202%5Ccos%20%5Ctheta%20-%5Cfrac%7B1%7D%7B2%7D%5Cright%20%5D%3D0)
as u cannot be zero therefore
