An object comes to an abrupt stop over 0.25 seconds with a change in momentum of 35 kg m/s . Determine the impulse associated with this example

how are the interactions between white light and an opaque object and between sunlight sunlight and Earth s atmosphere alike? How are they different

a sled mass 49.0kg is pulled along flat, snow covered ground. The static friction coefficient is 0.30, and the kinetic friction coefficient is 0.10

I don’t get it at all, I want to know the answer
