Question

A body of mass 0.5kg is thrown thrown horizontally on a horizontal rough surface with a velocity 10m/s .calculate acceleration and the distance b/w them..​

Answer 1

Explanation:

sorry video difficult what question I cannot know thank you have a nice day

Answer 2

Answer:

Explanation:

First use mass and velocity to find the kinetic energy,

ke = 0.5 * mass * velocity²

ke = 0.5 * 0.5kg * (10m/s)²

ke = 25J

Now find distance using gravitational potential energy equation,

because gpe = ke

gpe = mass * gravitational field strength * height (distance)

gpe = 0.5kg * 10m/s * x

25J = 5kgm/s * x

25/5 = x

x = 5m

Now we have distance, so we can find acceleration using this equation:

a=(v-u)²/2s

a= (10m/s-0m/s)²/(2*5m)

a= 10m/s²
