Question 3 / 10

A particle moves with v = 4t² m/s. Its displacement after 3 seconds is:

A12 m
B36 m
C48 m
D64 m
Class 11 · Physics · Kinematics✓ Correct +4

A particle moves with v = 4t² m/s. Its displacement after 3 seconds is:

B36 mYour answer ✓
Why

Displacement = ∫₀³ 4t² dt = [4t³/3]₀³ = 4·27/3 = 36 m. Integrate velocity over time — don't multiply v by t when v isn't constant.

In their words

A teacher who assigns it. A student who uses it.

Divakar SirTeacherPhysics Teacher · Mumbai
XamBaaz is a fantastic tool for any teacher looking to drive real concept clarity. It shows me which topics need re-teaching, while the NCERT-aligned adaptive practice keeps my students genuinely prepared for exam pressure. It's made monitoring student progress effortless and accurate. The platform's exam-grade marking and instant doubt-clearing with Genie help students to fix mistakes on their own.
AyushiStudentClass 9 Student · Mumbai
XamBaaz makes studying for school exams much easier. The concepts are explained in a simple way, and the quizzes help me practise and check how well I've understood each chapter. I especially like that I can learn a concept, practise it, and quickly see where I'm making mistakes. It makes exam preparation feel much less stressful and more organised.

What you're preparing for

Four exams, one syllabus, four marking schemes.

The biggest difference between these exams is the marking. Boards reward attempting everything. JEE and NEET cut marks for a wrong guess; MHT-CET does not. XamBaaz marks every quiz the way your exam does.
