Take acceleration of gravity = 9.8 m/s2 .
The ball stops rising and starts falling in (100/9.8) seconds.
It returns to the height of the bat in 2 x (100/9.8) = 20.408 seconds. (rounded)

The velocity is gravity acceleration x time or (9.8)(1.5) = 14.7 m/s. The velocity is not dependent on the mass.
a small airplane flies in a straight line at a average speed of 150 km/hour .how long dose it take the plane to fly 250 km
Assuming that air resistance can be ignored, s = ut + 0.5gt2 where s is the distance travelled = 324 feet, u is the initial velocity = 0 ft/sec, t is the time (in seconds), and g is the acceleration due to gravity = 32 ft/sec2 Therefore 324 = 0.5*16*t2 so that t2 = 20.25 and so t = 4.5 seconds.
It all depends on the initial velocity at which you fell, and whether air resistence is present, etc. If you are simply in a state of free fall, your time to reach the ground would be d=100m v1=0 a=9.8 <- acceleration of gravity on earth t=unknown d = Vi*t + 1/2 a t^2 100m=0*t+1/2(9.8) *t^2 100m=4.9*t^2 sqrt:(100m/4.9)=t

Assuming the acceleration due to gravity is -9.81 m/s^2, the time it takes for the baseball to hit the ground can be calculated using the formula: time = (final velocity - initial velocity) / acceleration. In this case, the final velocity will be 0 m/s when the baseball hits the ground. Calculating it would give you the time it takes for the baseball to hit the ground.
The speed of the baseball when it hits the ground is 150 m/s, assuming no air resistance. This is because the initial velocity will decrease due to gravity until it reaches zero at the highest point, and then starts to increase again as it falls back down.
This is a velocity question so u need to use uvaxt
To find the initial velocity of the kick, you can use the equation for projectile motion. The maximum height reached by the football is related to the initial vertical velocity component. By using trigonometric functions, you can determine the initial vertical velocity component and then calculate the initial velocity of the kick.
The initial velocity of a projectile affects its range by determining how far the projectile will travel horizontally before hitting the ground. A higher initial velocity will result in a longer range because the projectile has more speed to overcome air resistance and travel further. Conversely, a lower initial velocity will result in a shorter range as the projectile doesn't travel as far before hitting the ground.
The object's initial distance above the ground The object's initial velocity
The velocity of the tomato when it hits the ground will be determined by its initial velocity, the force of gravity acting upon it, and any air resistance. It will likely be accelerating towards the ground due to gravity until it reaches its terminal velocity upon impact.
The answer will depend on what "it" is, and on what its initial velocity is.
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
The speed of the baseball when it hits the ground will be approximately 150 meters per second, neglecting air resistance. The vertical velocity of the ball decreases as it goes up, eventually reaching zero at the peak of its trajectory, then increases as it falls back to the ground.
To answer this question one would need to know the rock's initial height and velocity.
