An object falls from the Transco Towerin Houstonand takes 15 seconds to reach the ground. A.What is its velocity at impact if air resistance is ignored?B. How tall is the building?C. What is its acceleration at the 2ndsecond? D. What is its acceleration at the 5thsecond? E. If the Transco Tower were actually 3,000 meters tall, how long would an object take to free-fall off of the top of the building? (ignoring air resistance) Someone help please!!

Arescue plane flying horizontally at spots a survivor in the ocean directly below and releases an emergency kit with a parachute. because of the shape of the parachute, it experiences insignificant horizontal air resistance. if the kit descends with a constant vertical acceleration of, how far away from the survivor will it hit the waves?

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.

If a negatively charged particle is placed at rest in an electric potential field that increases in the positive x-direction, what will the particle do? a. accelerate in the positive x-direction b. remain at rest c. accelerate in the negative x-direction
