Question

The initial velocity of a body is 10 m/s. After 5 s, the velocity of the body is 30 m/s. Its acceleration is ____ .​

Answer 1

Answer:

The initial velocity of a body is 10 m/s. After 5 s, the velocity of the body is 30 m/s. Its acceleration is 4m/s²

Explanation:

Given parameters,

• Initial velocity of the body = 10m/s
• Final velocity = 30m/s
• Time = 5 s

Acceleration is given by:

→ (v - u)/t

Where,

• v(final velocity) = 30 m/s
• u(initial velocity) = 10 m/s
• t(time) = 5 s

From the given parameters,

→ (30 - 10)/5

→ 20/5

→ 4 m/s²

∴ The acceleration of the body is 4m/s²

$\tt{acceleration}$

$\Large\underline{\pink{\underline{\frak{\pmb{solution}}}}}$

$formula = > \tt{a = \dfrac{v - u}{t} }$

$\tt{a = \dfrac{30 - 10}{5} }$

$\tt{a = \dfrac{20}{5} }$

$\tt{a = \dfrac{ \cancel{20}}{ \cancel{5}} }$

$\tt{a = \red{4 \: m/s ^{2} }}$
