270189 A body of mass\(2 \mathbf{k g}\) moving on a horizontal surface with an initial velocity of \(4 \mathrm{~ms}^{-1}\), comes to rest after 2 second. If one wants to keep this body moving on the same surface with a velocity of \(4 \mathrm{~ms}^{-1}\), the force required is

270190 Ten coinsare placed on top of each other on a horizontal table. If the mass of each coin is \(10 \mathrm{~g}\) and acceleration due to gravity is \(10 \mathrm{~ms}^{-2}\), what is the magnitude and direction of the force on the \(7^{\text {th }}\) coin (counting from the bottom) due to all the coins above it?

270191 A ball of mass 'm' moves normal to a wall with a velocity '\(u\) ' and rebounds with the same speed. The change in momentum of the ball during the rebounding is

270192 Bullets of\(0.03 \mathrm{~kg}\) mass each hit a plate at the rate of 200 bullets per second with a velocity of \(30 \mathrm{~m} / \mathrm{s}\). The average force acting on the plate in newton is

270193 A vehicle of mass\(10 \mathrm{~kg}\) is moving with a velocity of \(5 \mathrm{~ms}^{-1}\).To stop it in \(1 / 10\) sec the required force in opposite direction is
