Question

a car acclearates at a rate of 5 m/s² . find the increase in its velocity in 3 s​

Answer 1

Answer:

v = at

= 5×3= 15 is answer in question

Answer 2

Answer:-

Your answer is 15m\s

GIVEN:-

• acceleration(a) = 5m\s²
• Time(t)= 3s
• final velocity (v) = ?m\ s
• initial velocity (u) = 0 m\s

EXPLANATION:-

Using 1st equation of motion ,

$\tt \red{ \boxed{ \implies \bf \: v \: = u + at \: }}$

$\tt \implies \bf \: v = 0 + 5 \times 3$

$\tt \implies \bf \: v= 0+ 15$

$\tt \implies \bf \: v = 15m {s}^{ - 1}$
