(2)で9.8t=20を計算してt=2.04816...で有効数字から2.0sになることはいいんですが、(3)で2.04を使って計算していて今回みたいに割り切れなくて次の問題で使うって時どこまで値をとるんですか? 教えてください わかりにくかったら申し訳ないです

① 基本例題7 斜方投射 物理 高 基本問題 41,42 水平な地面から, 水平とのなす角が30° の向きに 速さ 40m/sで小球を打ち上げた。 図のようにx軸, 軸をとり、重力加速度の大きさを 9.8m/s2 として 次の各問に答えよ。を求め、 y 40m/s 30° 地面 x (1) 打ち上げてから0.20s 後の速度の成分 成分と, 位置のx座標, y 座標を求めよ。 (2) 打ち上げてから最高点に達するまでの時間を求めよ。 (3) 地面に達したときの水平到達距離を求めよ。 指針 小球は, x方向には速さ 40cos 30% m/sの等速直線運動をし, 夕方向には初速度 40sin 30°m/s の鉛直投げ上げと同じ運動をする。 最高点に達したとき, 小球の速度の鉛直成分は であり, 打ち上げてから地面に達するまでの時間 は、最高点に達するまでの時間の2倍となる。 「解説」 (1) 速度のx成分,成分は, √3 ひx=40cos30°=40x =20√3 2 =20×1.73=34.6m/s 35m/s Min v=vosino-gt=40sin30°-9.8×0.20 =40x- 12-1.96=18.0m/s 18m/s 位置のx座標, y 座標は, d x=vxt=34.6×0.20=6.92m 6.9m y=vesindt- 2 912 ×9.8×0.202 =40sin30°×0.20-12× =3.80m 3.8m (2) 求める時間は,v=0 となるときであり, v=vosine-gt」から, 0=40sin30°-9.8xt t=2.04s 2.0s (3) 水平方向には等速直線運動をし、地面に達 するまでに (2) で求めた時間の2倍かかるので、 x=vxt=34.6×(2.04×2)=141m 1.4×10m
