The rear wheels of a truck support 57.0%% of the weight of the truck, while the front wheels support 43.0%% of the weight. The center of gravity of the truck is 1.44 mm in front of the rear wheels. What is the wheelbase of the truck (the distance between the front and rear wheels)

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
