Web3 nov. 2007 · Given the above equation and the premise that the thrower can throw 60m from standing, I solved for v0 using vr=0, R=60, g=9.8, and θ=45° as that is the ideal throwing angle from standing. I found v0 = √ (60g). Next I tried to find the ideal angle to throw at when vr = 10 m/s. I did this by taking solving R' (θ)=0 where R' (θ) is the ... Web24. A runner at the start of a race generates 250 W of power as he accelerates to 5 m/s . If the runner has a mass of 60 kg, how long did it take him to reach that speed? 0.33 s. …

WebThe object thrown is a “projectile” and the path it takes is called “trajectory”. Here are some projectile motion examples: Firing a canon. Throwing a basketball at the basket. … WebThis equation was discussed in Unit 1 of The Physics Classroom. The equation can be written as follows. y = 0.5 • g • t 2 (equation for vertical displacement for a horizontally launched projectile) where g is -9.8 m/s/s and t is the time in seconds. The above equation pertains to a projectile with no initial vertical velocity and as such ... Web13 apr. 2024 · When thrown with perfect balance the javelin would keep climbing for a long time. More and more often the javelin would hit the ground while parallel to the ground, and would continue to slide for a distance. The javelin throw event became rather dangerous; sometimes the sliding javelin would slide all the way onto the running track. storage yellow pages
