Question

On June 25, 1983, shot-putter Udo Beyer of East Germany threw the $7.26-\mathrm{kg}$ shot $22.22 \mathrm{m}$, which at that time was a world record. (a) If the shot was released at a height of $2.20 \mathrm{m}$ with a projection angle of $45.0^{\circ},$ what was its initial velocity? (b) If while in Beyer's hand the shot was accelerated uniformly over a distance of $1.20 \mathrm{m},$ what was the net force on it?

Step 1

20 m - Projection angle, θ = 45.0° - Horizontal distance, r = 22.22 m Using the equation for horizontal distance: r = u cos θ * t Substitute the values: 22.22 = u * cos 45° * t Since t = 31.43/u (from the horizontal distance equation), we have: 22.22 = u * cos 45° Show more…
