What is q1?
Show answer
A 0.200.20 kg ball is thrown straight up at 1212 m/s. Ignoring air resistance, calculate the maximum height (g=9.8g = 9.8 m/s squared). [2 points]
What is q2?
Show answer
A 4.04.0 kg crate slides 5.05.0 m across a floor with μk=0.20\mu_k = 0.20 before stopping. Calculate the mechanical energy dissipated (g=9.8g = 9.8 m/s squared). [2 points]
