Astuntman drives a car with a mass of 1500 kg on a drawbridge. the car accelerates with a constant force of 10,000 n. while he is driving, the drawbridge is raised to an incline of 30°. what is the car's new acceleration on this incline, ignoring the force due to air resistance? (recall that g=9.8 m/s^2)

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
