Question 2 1 pts A 11.8 kg object is moving at a speed of 3.8 m/s. Another object is traveling at 11.9 m/s and has the same momentum as 11.8 kg object. What is the mass of the other object? Express your answer in kilograms and round to one decimal place. Question 3 1 pts A 87 kg physics professor is stranded on a frictionless lake initially at rest. To start moving they throw their treasured 7.1 kg physics book straight in front of them at 14.1 m/s. What is the speed of the physics professor after the book is thrown? Express your answer in meters per second and round to two decimal place.Question 3 1.5 pts A 8.6 g paper plate with a diameter of 27.6 cm is rotating about a fixed frictionless axis at 9.9 rad/s when a 0.89 g bug lands on the plate 8.3 cm from the fixed axis. Assume the bug had an initial velocity of zero right before it lands on the plate. You can treat the plate as a solid disk and the bug as a point mass. What is the angular speed of the plate after the bug lands on it? Express your answer in radians per second and round to one decimal place
