A stone thrown from the top of a building at a velocity of 16.0 m/s at an angle of 37° with the horizontal reaches the ground after 8.0 s. (a) What is the initial vertical velocity and initial horizontal velocity of the stone? (b) What is the height of the building? (c) What is the horizontal range of the stone? (d) What are the final vertical and horizontal velocities of the stone? (e) Where is the velocity and acceleration perpendicular and where is the velocity and acceleration parallel in a projectile motion?

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
