Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

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
