CHAPTER OF HUMAN MOVEMENT KINEMATIC CONCEPTS

Velocity is the ratio of displacement, or change in position, to the time taken (displacement divided by time). Velocity has both a size and a direction. velocity = displacement time The units for speed and velocity are metres per second or m/s. A change in velocity could be a change in speed, a change in direction, or both.

Step 1/2 First, we need to convert the angular velocity from degrees/second to radians/second. We know that 360 degrees = 2π radians. So, we have: 1700 degrees/second * (2π radians / 360 degrees) = 1700 * (2π / 360) radians/second ≈ 29.67 radians/second Now, we can find the linear velocity (v) using the formula: v = rω where r is the distance from the axis …

A 7.27 kg hammer on a 1 m wire is released with a linear velocity …

To determine the reaction force exerted on the thrower by the hammer at the instant before release, we can use the principle of conservation of momentum. Before release, the hammer is at rest. After release, the hammer moves with a linear velocity of 28 m/s. Since the hammer is the only object in motion, the total momentum before release is zero.
