Elena L [17]

Answer:

1.5 u

Explanation:

The range equation is:

R = u² sin(2θ) / g

When u = v, R = 2.25 R.

2.25 R = v² sin(2θ) / g

2.25 u² sin(2θ) / g = v² sin(2θ) / g

2.25 u² = v²

1.5 u = v

<h3>answer</h3>

The minimum velocity required for a object to rotate in a verticle plane is v

/r+mg=6mg.

At top-most point velocity is v

A wall, acted upon by a force of 20 N, does not move. The work done on the wall in this process is
prisoha [69]

0J

Explanation:

A wall that is acted upon by a force of 20N does not move suggests that no work has been done on the wall.

Work done is the force applied to move in the direction of the applied force.

   Work done = force x distance.

Since the distance is 0, the work done on the body too is zero.

Work is only done when forces moves a body through a given distance.
