Answer 1

Explanation:

Answer:

Given :-

Initial velocity of bus (U) = 0 m/s

Acceleration of bus (A) = 2 m/s

Time taken (T) = 4 m ➡ 240 second

To find :-

❶ Speed required

❷ Distance travelled

SoluTion

For find speed,

We will use newton first Equation

\fbox {v \: = u + at}

v = u + at

Here,

V = Final Velocity

U = Initial velocity

A = Acceleration

T = Time

\sf \: v \: = 0 + 2 \times 20v=0+2×20

\sf \: v \: = 0 + 40v=0+40

\sf \: \: v \: = 40 \: mpsv=40mps

Now finding distance travelled by using newton third Equation

\boxed { \sf \: s \: = ut + \dfrac{1}{2} \times a {t}^{2} }

s=ut+

Here,

S = Distance travelled

U = Initial velocity

T = Time taken

A = Acceleration

\sf \: s \: = 0 \times 20 + \dfrac{1}{2} \times 2 \times {240}^{2}s=0×20+

Answer 2

Answer:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. Wikipedia

In SI base units: kg·m/s2

Other units: dyne, pound-force, poundal, kip, kilopond

Derivations from other quantities: F = m a

SI unit: Newton
