ORIGINAL WRITTEN REHEARSAL
Jahangirnagar University Model Test for Exam
Choose a subject or the available combined paper. The 30- and 90-minute timers are practice options, not a claim about the institution’s current format. These original questions are not past papers. Answers stay in this browser; no school grade, coin balance or enrolment changes.
Set 1 of 1 available paper set.
5 written questions: 3 can be checked against the answer key; 2 need a guardian or subject teacher to review. Choose the relevant subjects for your target programme separately.
The timer starts when you choose Start model test.
You can leave or finish early without losing game progress. If time expires, the draft is kept and review opens. A timer is a rehearsal aid and cannot prevent leaving the page or changing a device clock.
Work on paper and enter the requested answer. Explain reasoning in the longer response boxes. Keep your work if you want a teacher to review it.
A 2 kg trolley at 3 m/s sticks to a stationary 1 kg trolley. External impulse during the collision is negligible. Compare total momentum and kinetic energy before and after.

Physics for the chosen programme
Some kinetic energy transfers to internal energy, deformation and sound.
Account for the energy rather than saying it disappears.
Physics for the chosen programme
Otherwise external forces can change the system’s total momentum during the collision.
Connect the condition to conservation.
The automatic result counts exact supported answer-key matches. Other valid wording, working, handwriting and compositions need human review. It is not an overall examination mark or an admission prediction.
