## At what angle should a ball hit to reach its maximum height?

45 degrees

A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees. But what about trying to maximize a projectile’s height to increase hang time? In a parabola the peak height attained by a projectile is equal to (sin(θ))² X v²/2g.

**What happens at the ball’s highest point?**

Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth (see figure 1).

### What happens to the projectile as it reaches the maximum height?

When a projectile reaches maximum height, the vertical component of its velocity is momentarily zero (vy = 0 m/s). However, the horizontal component of its velocity is not zero.

**What is the direction of acceleration for any projectile?**

Forces when unbalanced cause objects to accelerate; and the direction of the acceleration is in the same direction as the unbalanced or net force. For a projectile, the net force is the downward force of gravity; thus, the acceleration is downward.

#### How do you find the maximum height of a ball thrown up?

We know the value of g in SI is 9.8 m/second square. So just for example, if a ball is thrown vertically upwards with 98 m/s velocity, then to reach the maximum height it will take = 98/9.8 =10 seconds.

**Why is 45 degrees the best angle for projectile motion?**

As ball speed increases, so does the drag force and the lower is the required launch angle. A launch at 45 degrees would allow the ball to remain in the air for a longer time, but it would then be launched at a lower horizontal speed at the start and it would slow down more because of the longer flight time.

## How do you find the maximum height of a thrown object?

h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.

**When a ball reaches maximum height What is the acceleration?**

Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is: Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero….Objects Launched Upward.

Variable | Value |
---|---|

a | -9.8 m/s2 |

t | 0.40 s |

### What happens when a ball is thrown vertically upward?

When the body is thrown upwards, it moves up until the velocity of the ball becomes zero and the force exerted on it becomes zero. After that the ball reaches the ground with the acceleration due to gravity with the zero velocity. When the ball goes up, the height of the ball increases and it also moves up.

**What is the acceleration of a ball thrown upward at its highest point?**

The acceleration at the top of its motion is -9.8 meters/seconds squared. The direction of the ball is constant in a straight-upwards direction until it reaches its peak and then moves in exactly the opposite direction downwards.

#### When a ball is thrown vertically upwards?

**How much time is the ball in the air?**

It takes about 88 seconds for the cannonball to reach its maximum height (ignoring air resistance). You have 176 seconds, or 2 minutes and 56 seconds, until the cannonball destroys the cannon that fired it.
