If a 2 kg ball is thrown through the air at 20 meters per second what is the momentum of the ball?
The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the momentum of the 2 kg ball thrown at 20 m/s would be 40 kg*m/s.
What is the velocity of the object between 20 and 40 seconds?
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
A ball is thrown upward with an initial velocity of 20 meter per second how long is the ball in the air?
Assuming no air resistance or external forces, the ball will be in the air for the same amount of time it takes for it to return to the same height it was thrown from. The time the ball will be in the air can be calculated using the kinematic equation: time = (2 * initial velocity) / gravitational acceleration. So, in this case, the ball will be in the air for approximately 4 seconds.
A ball is dropped from a window and takes 2 seconds to reach the ground. It starts from rest and reaches a final speed of 20 MS What is the balls acceleration?
The acceleration of the ball can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the initial velocity is 0 m/s, the final velocity is 20 m/s, and the time is 2 seconds. Therefore, the acceleration would be (20 m/s - 0 m/s) / 2 s = 10 m/s^2.
What is the velocity of a soccer ball kicked into the goal that is 28 meters away and it arrives in 1.4 seconds?
Velocity = Distance/Time = 28/1.4 = 20 m/s
If a ball rolls off the edge of a table two meters above the floor and with an initial velocity of 20 meters per second what is the ball?
The time it takes for the ball to hit the floor is approximately 0.64 seconds.
A ball is thrown straight up from a platform 5 feet above the ground with an initial velocity of 20 feet per second Write an equation that you can use to find how long the ball was in the air?
Height = H0 + V0 T +1/2a T2H0 = height when released = +5V0 = velocity when released = 20 up = +20a = acceleration of gravity = 32.2 down = -32.2When the ball hits the ground, "Height" = 05 + 20 T - 16.1 T2 = 0Easier . . . 16.1 T2 - 20 T - 5 = 0Quadratic formula: T = 1/32.2 [ 20 +/- sqrt(400 + 322) ]T = (20 +/- 26.87) / 32.2T = -0.213 secondsT = 1.456 seconds (rounded)
What is an example problem of speed and velocity?
An example problem involving speed is calculating the average speed of a car that travels 100 miles in 2 hours. An example problem involving velocity is determining the velocity of a ball thrown upward with an initial velocity of 20 m/s at a height of 40 meters above the ground.
What is the terminal velocity of a cream pie thrown by a human?
The terminal velocity of a cream pie thrown by a human would depend on various factors such as the size, weight, aerodynamics of the pie, and the speed at which it is thrown. However, in general, the terminal velocity of a typical cream pie might range from 20-50 miles per hour.
What is the acceleration of car that increase its speed by 10 milessec after 30 seconds if the initial velocity was 20 milessec?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 20+10 = 30 miles/sec, the initial velocity is 20 miles/sec, and the time is 30 seconds. So, the acceleration of the car is (30 - 20) / 30 = 0.33 miles/sec^2.
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.
If a train is accelerating at a rate of 4km per hour per second and its initial velocity is 20km per hour what is its velocity after 30 seconds?
The train's velocity after 30 seconds can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Plugging in the values, final velocity = 20 km/hr + (4 km/hr/s * 30 s) = 20 km/hr + 120 km/hr = 140 km/hr. So, the train's velocity after 30 seconds is 140 km/hr.
