During a collision a 9.50x10 2 kg car’s front end crushes in 1.35 m. (The car travels 1.35 m in coming to a stop.) If the car was traveling at 35.0 m/s before the collision, find the net force on the car.

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

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
