At time (t=0 ), a car moving along a straight line has a velocity of (16 ~ms ⁻¹ ). It slows down with an acceleration of (-0.5 t ~ms ⁻² ), where (t ) is in second. Mark the correct statement (s).

Options

  1. AThe direction of velocity changes at (t=8 ~s )
  2. BThe distance travelled in 4 s is approximately 58.67 m
  3. CThe distance travelled by the particle in 10 s is 94 m
  4. DThe speed of particle at (t=10 ~s ) is (9 ~ms ⁻¹ )

Correct answer

A. The direction of velocity changes at (t=8 ~s )

Step-by-step solution

This typically indicates that all given statements or options are correct in the context of the question. Without the specific question, a detailed explanation for each part is not possible, but it implies all conditions or descriptions are true.
