Question

a projectile is projected in xy plane vertical with initial velocity of you equals to 3 ICAP + 4 j cap metre per second velocity at the highest point is .........m/s

Answer 1

The question relates Two Dimensional Kinematics to Projectile Motion.

We will consider motion in X and Y directions individually, and go from basics of Kinematics.

We have:

The two components are:

Also, there's the gravitational acceleration acting in the negative Y direction. So,

There is no acceleration in the horizontal direction. So, the horizontal velocity is going to remain constant.

For Range, we just need to know the Time of Flight. We can then multiply it with to get the answer.

Time of Flight (T) is the Time between the projection and the body hitting the ground.

So, we see when the vertical displacement becomes zero after the projection. That will give us Time of Flight.

In Y-direction,
