Question

If a body is travel at a speed of 5m/s after 2 second it speed increase by 10m/s find acceleration

Answer 1

Answer:

2.5 m/s

Explanation:

Here,  

Initial velocity = u = 5 m/s

time = t = 2 s

Final velocity = v = 10 m/s

now acceleration a = $= \frac{v - u }{t}$

                                   $\\\\\\= \frac{10 - 5 }{2} \\\\\\= \frac{5}{2} \\\\= 2.5 \frac{m}{s}$
