In a physics lab, a 0.5 kg cart moving with a speed of 1.3 m/s collides with a 1.5 kg cart that is initially at rest. The 0.5 kg cart rebounds with a speed of 0.45 m/s in the opposite direction. Fill in the table to calculate the momentum and velocity of the 1.5 kg cart after the collision.

The plum pudding model of the atom states that ?

How do we measure or think of speed in the united states?

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
