Given:
The initial velocity of the projection, u=50 m/s
To find:
The velocity of the missile at the highest point of its projection.
Step-by-step explanation:
The missile will be traveling under the influence of acceleration due to gravity. Thus, as the missile rises through the atmosphere, it slows down due to the downward acceleration acting on it. Thus the missile will come to rest eventually, i.e., its velocity becomes zero. After this, the missile changes its direction and starts to move downwards due to the acceleration due to gravity.
Thus, at the highest point of its projection, the velocity of the missile will be zero.
Final answer:
The velocity of the missile at the highest point of its projection is zero meters per second.
