STEP 1: Determine horizontal(x) and vertical (y) components of the initial velocity of golf ball. Vy=Vsin55 = 50x.8191= 40.9 m/s, Vx=Vcos55 = 50x.5735= 28.6 m/s STEP 2: At maximum height, Vy=0. Determine time (t) it takes to reach max. height.
First, Jesse covers 6 miles in 1 hour at 6 miles per hour (60 minutes). If his new speed is 7 miles per hour: Velocity= Distance/Time Solve for Time(T): TIME(T) =DISTANCE/VELOCITY...becomes: T(hr)=(6 miles X 1HR)/7 miles Miles cancel, leaves
