Sample questions with model answers
Every question in the paper gets a full exam-length answer in the app — organised by marks, the way a topper writes it.
A particle moves along the X-axis from $x = 0$ to $x = 5$ m under the influence of a force given by $F = 7 - 2x + 3x^2$. Find the work done in the process.
Show answer outline
Work done is calculated using $W = \int F \, dx$.

Prove that the time of flight T and the horizontal range R of a projectile are connected by the equation $gT^2 = 2R \tan \theta$ where \( \theta \) is the angle of projection.
Show answer outline
Use kinematic equations to derive the relation.

(a) What is escape velocity? Derive its expression and give its value for Earth.
Show answer outline
Escape velocity is $v_e = \sqrt{\frac{2GM}{R}}$; for Earth, $v_e \approx 11.2 \, km/s$.

A body starting from rest accelerates uniformly along a straight line at the rate of $10 m/s^2$ for 5 s. It then moves for 2 s with uniform velocity of 50 m/s. Then it retards uniformly and comes to rest in 3 s. Draw velocity-time graph of the body and find the total distance traveled by the body.
Show answer outline
Total distance is calculated from the area under the velocity-time graph.
