You (mass of 65 kg) roll out of bed at an unknown velocity. How fast are you rolling if you have 468,000 J of KE? answer =
KE = 5mv2
I really need help

What is the measurement of how fast an object moves relative to a reference point?

Will mark as brainliest how does a catapult increase the trajectory of an object? ps. answer as if u were a 5th grader

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 .
