Answer 1

B: 10.5s pc.3.5sbdnshd habsbdjebs

Answer 2

• initial velocity=u=7m/s
• Final velocity=v=0m/s
• Acceleration=a=-3.5m/s^2

$\\ \rm\Rrightarrow v=u+at$

$\\ \rm\Rrightarrow t=\dfrac{v-u}{a}$

$\\ \rm\Rrightarrow t=\dfrac{0-7}{-3.5}$

$\\ \rm\Rrightarrow t=\dfrac{-7}{-3.5}$

$\\ \rm\Rrightarrow t=2s$
