Question
x = 300 cos 25 degree t. We can get the time in flight by examining the distance that the ball falls in the y direction -120 = 300 sin 25 degree t - 1/2 9.8t^2. Solve the above equation for the time in flight and then the x distance the ball travels. A boy tosses a ball into the air. Using this figure, identify the point at which: the velocity of the ball is zero. the acceleration of the ball is zero. the absolute value of the velocity is a maximum. the acceleration is a maximum. Be sure to include your reasoning for each.Explanation / Answer
velocity of ball is zero.
- At maximum height
Acceleration of ball is zero.
- Acc is always 9.8 m/s^2 donward. hence acceleration is always non-zero.
Absolute value of velocity is maximum.
- atlowest point
Acceleration is a maximum.
- acceleration is same everywherre.
