C
F
D 2) A bus start from rest and accelerats with uniform
acceleration 1m/s2. Catculate the velocity of
the bus after 10s.​

Answer 1

Given:-

• A bus starts from rest.
• It has aacclⁿ of 1m/s².

To Find:-

• The velocity of bus after 10 s.

Formula Used:-

$\large{\underline{\boxed{\green{\bf{\dag \:\:v\:\:\:\:=\:\:\:\:u\:\:+\:\:at }}}}}$

where ,

• a is acceleration.
• u is Initial velocity.
• v is final Velocity.
• t is time taken.

Calculation:-

➤ Initial velocity of bus = 0m/s .

➤ Acceleration of bus = 1m/s².

➤ Time of acclⁿ = 10s .

Now , putting the values in above formula stated ,

$\tt:\implies v = u + at$

$\tt:\implies v = 0m/s + 1m/s^2 \times 10s$

$\tt:\implies v = \dfrac{1m}{s^{\cancel{2}}}\times 10\cancel{s}$

$\underline{\boxed{\red{\tt{\longmapsto v \:\:\:\:=\:\:\:\:10ms^{-1}}}}}$

$\underline{\tt{\pink{\dag Hence\:the\: Velocity\:after\:10s\:is\:10m/s.}}}$
