Answer:
His performance would improve
Explanation:
This is because, he now has a larger distance to cover in the 10.0 ft diameter circle. This increased distance would cause him to give a greater angular speed to his whirl and thus a greater tangential velocity to the shot put. This greater speed would thus cause the shot put to travel more in the 10.0 ft diameter circle throw than in the 7 ft 6 in diameter circle throw.
Hi there!
The formula for velocity given acceleration:
v = at
Plug in given values:
v = 6.4(7) = 44.8 m/s
<u>The force of friction is the necessary force which helps us to walk on ground. The friction is generated between the shoes and the road. We press the ground and as a reaction the ground pushes us forward. The force of friction between sole and ground provides the necessary grip which pushes us forward.</u>
