अ बॉडी इनिशियली अट रेस्ट स्टार्टस मूविंग विद कांस्टेंट एक्सीलरेशन 2 मीटर पर सेकंड स्क्वायर कैलकुलेट द वेलोसिटी रिक्वायर्ड एंड द डिस्टेंस ट्रैवल्ड इन 7 सेकंड​

Answer 1

Explanation:

Here,,

Initial velocity of the body,u=0 m/s

Acceleration of the body,a=2 m/s²

Time taken by the body,t=7s

To find,,

Velocity acquired,v=??

and, Distance travelled,s=??

Using,,

$\mathbf{\boxed{v=u+at}}$

we get,,

$\sf{v=0+2\times{7}}$

$\sf{\boxed{v=14 m/s}}$

Therefore,, velocity acquired,v=14m/s

$\rule{200}2$

Now Using,,

$\mathbf{\boxed{</strong><strong>s</strong><strong>=</strong><strong>ut</strong><strong>+</strong><strong>\</strong><strong>f</strong><strong>r</strong><strong>a</strong><strong>c</strong><strong>{</strong><strong>1</strong><strong>}</strong><strong>{</strong><strong>2</strong><strong>}</strong><strong>at^</strong><strong>{</strong><strong>2</strong><strong>}</strong><strong>}}$

we get,,

$\sf{</strong><strong>s</strong><strong>=</strong><strong>0</strong><strong>+</strong><strong>\</strong><strong>c</strong><strong>a</strong><strong>n</strong><strong>c</strong><strong>e</strong><strong>l</strong><strong>\frac{</strong><strong>2</strong><strong>}{2}</strong><strong>\</strong><strong>t</strong><strong>i</strong><strong>m</strong><strong>e</strong><strong>s</strong><strong>{</strong><strong>7</strong><strong>^{2}</strong><strong>}</strong><strong>}$

$\sf{</strong><strong>\</strong><strong>i</strong><strong>m</strong><strong>p</strong><strong>l</strong><strong>i</strong><strong>e</strong><strong>s</strong><strong>{</strong><strong>\boxed{v=</strong><strong>4</strong><strong>9</strong><strong>m</strong><strong>}</strong><strong>}}$

Therefore, distance travelled,s=49m

$\rule{200}2$

Hope it helps ❣️❣️❣️
