The potential energy as it reaches a height of 0.63 meters is mgh
Since total mechanical energy is conserved, Set that equal to the initial kinetic energy which is 0.5mv^2
2*9.8*0.63 = 0.5*2*v^2
12.348 = v^2
3.51 = v
That's it's initial speed.
Answer:
So the weight of the body is 700N
Explanation:
mass of the object=70kg
force of gravity=10N/kg
weight of the object=w-?
as we know that
weight=mass × force of gravity
weight=70kg × 10N/kg
WEIGHT OF THE BODY=700N

Answer:
Explanation:
Given:
- Linear horizontal speed of the ball,
- distance travelled by the ball,
- angle rotated by the ball,
- radius of the ball,
<u>the time for which the ball travels:</u>
<u>Angular speed of the ball:</u>
<u>Now the tangential speed at the equator of the ball:</u>
(the tangential speed due to rotation and the linear speed are having the same direction)
