Question

Numerical on second equation of motion

Answer 1

Explanation:

Q . A jet plane starts from rest with an acceleration of 3 metre per second square and make a run for 35 seconds before taking off. What is the minimum length of the Runway and what is the velocity of Jet at take off .

Q. An electron travelling with a speed of 5 × 10^3 m / sec pass through an electric field with an acceleration of 10^12 m / sec^2 .

i. how long will it take for the electron to double its speed ?

ii. what will be the distance covered by the electron in this time ?

Best of luck to solve these problems .
