Answer:
<h2>D</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question
mass = 2 kg
velocity/speed = 3 m/s
We have
momentum = 2 × 3 = 6
We have the final answer as
<h3>6 kg.m/s</h3>
Hope this helps you
Density=mass÷volume
mass=density×volume
mass=2×8=16 g
"New York, New York" becomes the official anthem of New York City
Marshall U's Bruce Morris scores a basket from 92'5".
NY Devil Don Lever becomes 57th NHLer to score 300 goals.
At the top of the height, the velocity is zero and acceleration is negative of acceleration due to gravity ( i.e
).
The time of the ball in air is 3.2 s, so ascending time is
.
Therefore from kinematic equation,

Substituting the values we get,
, Here v = 0 at top.
Now from equation,
, here h is the height .
So,
.
Thus, the ball reached at its maximum height of 12.48 m.
