The momentum of a body is increased by 25
WebApr 24, 2024 · Hello Aspirant! We know that - Momentum (p) = m x v where, m=mass of the object v= velocity of the object => v = p/m Now, Kinetic Energy (K. E.) = (1/2) x m x (v)^2 Substituting the value of v = p/m in this equation, we get - K. E. = (1/2) x m x (p/m)^2 = (1/2) x (1/m) (p^2) According to the question, for 20% increase in momentum, kinetic energy will … WebIf momentum is increased by 20%, then kinetic energy increases by A 48% B 44% C 40% D 36% Easy Solution Verified by Toppr Correct option is B) The kinetic energy is given by KE= 2mp 2 So, ΔKE= 2m2pΔp= mpΔp ⇒ KEΔKE= mpΔp× p 22m= p2Δp Since the momentum p increases by 20%, so the final momentum becomes 1.2p.

Key Points Momentum can be defined as the product of the mass of a particle and its velocity. It is denoted by p , SI unit is (Kg-m)/s and Dimension is MLT−1. Newton's second law defines a force to be equal to the change in momentum with a change in time. Additional Information
WebMomentum is defined as the quantity of motion of the body. It is measured by “mass × velocity”, as momentum depends upon velocity, and it depends on the direction of the motion of the body as well. Momentum is a vector quantity since velocity is a vector while mass is scalar. Momentum = Mass X Velocity p = mv SI Unit: Kg.m.s -1 WebAs you can see from the blue (momentum) and red (energy) lines below, the amount of increase in kinetic energy for a given increase in momentum depends on the velocity you start at: Counterintuitively, it means you get a bigger increase in energy the faster you were going to begin with.
WebApr 6, 2024 · Note: -Whenever we get this type of question the key concept of solving is we have to have knowledge of relation between linear momentum and kinetic energy and using new linear momentum we have to find new kinetic energy and hence find increase in kinetic energy from which increase in percentage of kinetic energy.Kinetic energy can also be ... WebApr 9, 2024 · Hint: Using the formula for momentum and kinetic energy, derive an expression such that kinetic energy is equated in terms of the momentum of the object. Then, for the change of momentum find the corresponding change in the kinetic energy of the object and find the percent change.
WebWhen the momentum of a body is increased by 25%, its momentum will become p′ = p+ 10025 p = 100125p = 45p ∴ KK′ = p2p′2 = (45)2 = 1625orK ′ = 1625K Percentage increase …
