We will use two definitions to solve this problem. The first will be given by the conservation of energy, whereby the change in kinetic energy must be equivalent to work. At the same time, work can be defined as the product between the force by the distance traveled. By matching these two expressions and clearing for the Force we can find the desired variable.
Thus the force acting on the sled is,
Replacing,
Therefore the Force acting on the sled is 32N
Answer:
The value is
Explanation:
From the question we are told that
The total time of flight is
Generally from kinematic equation
So v is the velocity at maximum height and the value is v = 0 m/s
So
=>
Here u is the initial velocity of the dart as it leaves that gun
Gnerally the horizontal range of the dart is mathematically represented as
For maximum horizontal range the value of
So
=>
