Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 3/5

A simple pendulum of length 80 cm has a bob of mass 100 g. The bob is released from rest with the string held horizontal and taut. Taking g = 10 m s⁻², the speed of the bob at the lowest point of the swing is

A. 2 m s⁻¹
B. 2.8 m s⁻¹
C. 8 m s⁻¹
D. 4 m s⁻¹

Example 2 · difficulty 2/5

An electric motor raises a 500 kg load vertically upward at a constant speed of 2 m s⁻¹. Neglecting friction and air resistance, and taking g = 10 m s⁻², the power delivered by the motor is

A. 10 kW
B. 2.5 kW
C. 5 kW
D. 20 kW

Example 3 · difficulty 4/5

A 2 kg sphere sliding at 3 m s⁻¹ on a frictionless floor collides head-on and elastically with a stationary 1 kg sphere. The speed of the 1 kg sphere immediately after the collision is

A. 1 m s⁻¹
B. 2 m s⁻¹
C. 4 m s⁻¹
D. 6 m s⁻¹

The evidence-first practice loop

1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
2. Attempt closed-bookExpose the concept or execution gap before rereading.
3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2017 Physics Work, Energy and Power PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2017 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
