##### Reference no: EM13544665

Bob (m = 60kg) is wearing a sticky suit. Just as he reaches his desired speed of 6m/s, he reaches the edge of ice (assume the ice is frictionless) and collides with a large crate (m = 250kg). Bob and the crate stick together and slide along level ground (uk = 0.60). a) How far do Bob and the large crate slide before coming to rest? b) How elastic was the collision? c) How much thermal energy has been generated during the slide?
