Question

Q1.

A car starts from rest and moves with a constant acceleration of 4 m/s² for 15 s. Calculate

Final velocity
Total displacement
Average velocity

Answer 1

Answer: C (0 m)

Answer 2

Answer: C

Answer 3

Answer: C

Answer 4

Answer: 20 m/s

Answer 5

Answer: 200 m

Answer 6

Answer: 40 m/s

Answer 7

Answer: A

Answer 8

Answer: Straight line on displacement–time graph

Answer 9

Answer: Zero

Answer 10

Answer: 45 m

Answer 11

Final Answer: μₛ = 0.27

Answer 12

When a block just begins to slide on an inclined plane, the coefficient of static friction is equal to the tangent of the angle of inclination.

μₛ = tan 15° = 0.27

Answer 13

Final Answer:

a_max = 1.5 m/s²
