How does the kinetic energy of a body affected if its mass is doubled and velocity is reduced to one third? Expert-Verified Answer (1)Its mass is double-The kinetic energy becomes two times. (2)Its velocity is reduced to one-third of the initial velocity-The kinetic energy reduces to one-ninth of its initial value. What is the effect […]

What is the kinetic energy of a body of mass 20 kg is moving with a velocity 5m s? The correct answer is 250 J. Given, mass (m) = 20 kg, velocity (v) = 5 ms-1. So, the kinetic energy of the object is (½)∗20∗52 = 250 J. How does the kinetic energy of a

How momentum is conserved when a ball bounces against the floor? After collision ,the floor (earth) also attains momentum in the opposite direction of momentum of the ball to maintain the momentum of the ball. As momentum is conserved so Initial linear momentum is equal to final linear momentum. Which has greater kinetic energy? Also,

How do you find the velocity of a ball after a collision? What is the formula of collision? From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v’1 + m2v’2. If the collision is perfectly inelastic, the final velocity of the system is determined using v’ =

Is a bullet from a gun kinetic or potential energy? A bullet fired from a gun possesses kinetic energy due to its state of motion. What is a 20 g bullet moving at 1000 m s is fired through? A 20g bullet moving at 1000 m/s is fired through a one kg block of wood

When a particle of mass 2kg starts moving from rest? Expert-Verified Answer GIVEN:- A particle of mass 2kg starts moving from rest under the application of a single unidirectional force given as F = 8t, where t is time in seconds. Hence, the work done by the force on the body during the first 3

When two carts having the same mass and the same speed collide and stick together? If both carts have the same masses and speeds then they will both come to rest after they hit the Velcro pads. This collision is completely inelastic: all the kinetic energy disappears. It is hardly necessary to do any mathematical

What is the acceleration of a 2 kg ball moving with a constant speed of 5 m s? Final answer: The acceleration of a 2-kg ball moving with a constant speed of 5 m/s in a horizontal circle of radius 50 cm is calculated using the formula for centripetal acceleration, resulting in a value of

What is the velocity of a body of mass 2kg changes from? The velocity of a body of mass 2 kg changes from v1= 2ˆi+3ˆj−ˆk m/s to v2=−3ˆi+2ˆj+3 ˆk m/s in 3 sec under the influence of a external force. Is a small sphere of mass 1kg moving? A small sphere of mass m=1kg is

What is a 2 kg particle moves along an x-axis its position? A 2.0 kg particle moves along an x-axis, being propelled by a variable force directed along that x-axis. Its position is given by x = 3.0 m + (4.0 m/s)t + ct2 – (2.0 m/s3)t3, with x in meters and t in seconds.
