The horizontal component of the velocity of the ball is calculated by multiplying the speed by the cosine of the given angle. x-component of speed = (31 m/s)(cos 35°) = 25.39 m/s Thus, the horizontal velocity component of the ball is 25.39 m/s.
As we know that if a vector is inclined at some angle with the horizontal then the component of the vector along and perpendicular to horizontal is given as
now here we need to find the component of velocity
so we know that
now we will have
so horizontal component of the speed will be 25.4 m/s
The exosphere is the layer of the atmosphere "Where gas molecules can be exchanged between Earth's atmosphere and outer space." Thus, the answer would be C.
I think golf does not demand high level of physical fitness. A golfer just need be skillful and able to play under pressure. In terms of physical exercise i think he/she just need to do some muscle stretches.
