Abody a of mass 1.5kg, travelling along the positive x-axis with speed 4.5m/s, collides with another body b of mass 3.2kg which, initially, is at rest. as a result of the collision, a is deflected and moves with a speed 2.1m/s in a direction which is at angle 30° below the x-axis. b is set in motion at an angle θ above the x-axis. calculate the velocity of b after the collision

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
