If an arrow is shot upward on the moon with a velocity of 55 m/s, its height after t seconds is given by h = 55t - 0.04t2 . Find the (instantaneous) velocity over at t = 10 sec.

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

At an oceanside nuclear power plant, seawater is used as part of the cooling system. this raises the temperature of the water that is discharged back into the ocean. the amount that the water temperature is raised has a uniform distribution over the interval from 10° to 25° c. what is the standard deviation of the temperature increase?
