A swimmer who can consistently keep the same pace to cover 50 meters in 8.41 seconds sets out to swim across a river. The current in the river moves at 2.94 meters per second as the swimmer keeps a constant pace trying to get directly across (at a right angle to the current). What is the actual speed of the swimmer compared to land?

A cheetah is squatted 25m to the east of a vehicle. At time t = 0 the cheetah begins to run due east toward an antelope that is 55m to the east of the vehicle. During the first 2.0 s of the chase,the cheetah’s x-coordinate varies with time according to the equationx = 25m + (4.5m/s2)t2. (a) Find the cheetah’s displacement between t1= 1.5s and t2= 3.0 s. (b) Find its average velocity during that interval. (c) Find its instantaneous velocity at t= 2.5s by taking Δt = 0.15s.
