The velocity of a moving vehicle is given by the equation v = (2t + 3)4 e task is to: a) Use the Chain Rule to determine an equation for the dv acceleration when a = dt

A motorboat maintained a constant speed of 15 mph relative to the water and going 44 miles upstream and then returning the total time for the trip with 7.5 hours use this information to find the speed of the current

a) What is the function expressing the altitude (vertical position) of the key if the altitude measured by GPS when you drop the key (at the top) is 1,500 m? b)If the key arrives at the bottom of the cliff with an (absolute) speed of 15.2 m/s, what is the height of the cliff (the difference between the altitude at the start and at the finish)?

A projectile is launched with an initial speed of 785 m/s  additionally V(iy) =736 m/s and V(ix) =-273 impact occurs at the same altitude it was launched at determine the following values take up to be positive

Can someone help me answer this question with all the steps included pls and thank you!!
