A projectile is fired from the surface of the earth with a velocity of 5ms−1 and angle θ

To prepare for IIT-JEE Physics, focus on understanding concepts rather than memorizing formulas. Practice solving a variety of problems, especially previous years’ questions. Create a study schedule that covers all topics, with extra time for challenging areas like Mechanics and Electromagnetism. Regular revision and mock tests are essential for success.

To solve projectile motion problems, break the motion into horizontal and vertical components. The horizontal motion has constant velocity (a_x = 0), while the vertical motion has constant acceleration due to gravity (a_y = g). Use the equations of motion separately for each component, and remember that the time is the same for both components.

To solve physics numerical problems effectively, first understand the concept thoroughly. Then follow these steps: 1) Read the problem carefully and identify the given quantities and what needs to be found. 2) Draw a diagram if applicable. 3) Write down the relevant formulas. 4) Substitute the values with proper units. 5) Solve step by step. 6) Verify your answer by checking units and whether the result makes physical sense.
