What speed must you toss a ball straight up so that it takes 4 s to return to you?
To toss a ball straight up so that it takes 4.0 seconds to return to you, it must be thrown at a speed of 19.6 meters per second. This is because it will have a speed of zero at 2.0 seconds, therefore it must have a speed of 19.6 meters per second for gravity's 9.8 meters per second squared to slow it to zero in 2 seconds.
What else can I help you with?
A ball being thrown at 150kph takes how low to travel 20meters?
To calculate the time it takes for the ball to travel 20 meters, we first convert the speed to m/s: 150 km/h = 41.67 m/s. Then, we use the formula: time = distance/speed. Therefore, the ball takes approximately 0.48 seconds to travel 20 meters.
Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?
The speed of the ball is greatest when it is thrown upward and decreases as it reaches the peak of its trajectory. The speed continues to decrease as the ball falls back down due to the force of gravity pulling it towards the ground.
If a person in a train moving at high speeds threw a ball straight into the air would the ball continue at the same speed as the thrower or would it travel a different speed?
The ball would continue to move at the same speed as the train in the horizontal direction, but its vertical speed would be affected by gravity. The overall motion of the ball would be a combination of the horizontal motion at the speed of the train and the vertical motion due to gravity.
Is a ball rolling in a straight line at a constant speed in equilibrium?
Yes. Because it is moving at a constant speed, we know that it is not accelerating (changing its speed). This means that all forces acting on it are balancing each other, so the net force is 0.
What is an example of constant motion?
A ball rolling at a constant speed at the same rate of speed on a still surface.
What is a bowling approach?
a bowling approach is the steps a person takes before actually throwing the ball. the approach is also the area that starts at the end of the ball return up to the foul line.
What bowling shot does not curve?
The straight ball.
A baseball player hits a foul ball straight up in the air it leaves the the bat with the speed of 120 km in absence of air resistance how fast will the ball be traveling when the catcher catches it?
The ball will be traveling at the same speed when it returns to Earth.

How fast should a fast ball go?
Speed doesn't matter for fast balls, what matters is if it's going straight or not.
How long will it take the ball to return to earth when it is thrown straight upward at 150' per second at the height of 5'?
OW! Not long enough!
What happens to a ball thrown straight down from a bridge would have acceleration of?
The ball thrown straight down from a bridge will experience an acceleration due to gravity. On Earth, this acceleration is approximately 9.81 m/s^2 and acts in the downward direction. The acceleration will cause the ball to increase in speed as it falls towards the ground.
