What force is moving a toy car? EXPLANATION: From the above figure, it is clear that when we move a toy car on the ground with our hand, then the frictional force (FL), gravity (mg), and the reaction of the ground...
What is the contact time between the ball and the bat? The contact time between the baseball and bat is less than 0.001 seconds (a little less than one frames of the movie). Other measurements suggest a contact time of about...
What is the physics of momentum in baseball? When the bat collides with a ball, you are transferring the momentum (the product of mass times velocity) from the bat to the ball. To maximize the momentum of the bat, you can...
What type of energy is hitting a baseball? The kinetic energy of the bat is transferred to the ball. The mass of the ball increases, so it gains kinetic energy. The ball gains potential energy from the bat. Does a tennis...
How much work is done to move a 1400 kg car? Hence, the work done against the friction =20300 J. A car weighing 1400 kg is moving at a speed of 54 km/h up a hill when the motor stops. If...
What is the direction of acceleration if the car is moving to the right and slowing down? Direction of Acceleration: If an object is slowing down, then the direction of its acceleration is opposite the direction which the object is moving....
Is a 1000 kg vehicle moving with a speed of 20 meters per second is brought to rest in a distance of 50 meters A 1000 kg vehicle moving with a speed of 20m/s is brought to rest in a distance...
What is a 500kg car moving with a velocity of 36km h? Power=500×30×102×60=1250W. What would be the net force on the car if it were moving to the left? A)If a car is moving to the left with constant velocity then...
What will happen to kinetic energy of a body if its velocity becomes 4 times the original velocity? m is the mass of the body, v is the speed of the body. Now, the speed is four times. So the kinetic...
What is the conservation of momentum in 2d? For a collision where objects will be moving in 2 dimensions (e.g. x and y), the momentum will be conserved in each direction independently (as long as there’s no external impulse in that...
