- A rabbit runs across a parking lot. The coordinates of the rabbit's position (in meter) are given by x=23.4t and y=x/2,5 where t is in seconds. Determine the magnitude of the acceleration at t=2s in m/s.A high-tech drone flies over Miami, FL in a direction 50.4 west of north with a speed of 35.4 km/h. Three hours later, the drone suddenly shifts due north, and its speed slows to 19.2 km/h. How far (in kilometers) from Miami, FL is the drone 4.50 h after it passes over the Miami. Round your answer to 0 decimal places.The acceleration of gravity is approximately 9.81 m>s2 (depending on your location). What is the acceleration of gravity in feetper second squared?
- A car is traveling around a circular track of 720-ft radius. If the magnitude of its total acceleration is 4.4 ft/sec² at the instant when its speed is 33 mi/hr, determine the rate aț at which the car is changing its speed. Answer: aț = ± i ft/sec?A space shuttle’s coordinates as functions of time are given by x(t) = 7.0 t^3 and y(t) = 4.0t^2 - 2.1t , where x and y are in meters and t is in seconds. What is the distance of the space shuttle to the base 1 minute after it has been launched ?A stone accidentally falls from rest from the edge of a 35-m-high building. When the stone is 14m above the ground, a man, 2m tall, looks up and notices that the stone is directly above him. Determine the time (in sec),at most, the man has to get out of the way.0 the answer must be 3 decimal places.

Answers: r = 0 = i i 18 Ma V. ft/sec deg/secA diver jumps off a cliff of height h at an angle θ = 260 (see figure). He reaches a maximum height of h subscript m a x end subscript= 20 m above the top of the cliff before falling to the water below. He hits the water x=295 m from the base of the cliff. Determine the height of the cliff, h. Take g=10m/s2 . Round your answer to one decimal place.A group of hikers sets out going 10.0km [N], then 15.0km [E], then 4.0km [S]. The entire trip takes 4.00h. Determine the magnitude hikers' distance for the trip.
- A boat has an initial speed of 19 ft/s. It then increases its speed along a circular path of radius ρ = 80 ft at the rate of v˙=(1.4s)ft/s^2, where s is in feet. Determine the time needed for the boat to travel s = 70 ft.A motorist goes for a drive, keeping the reading on the speedometer at a constant value of 40km/h. The speedometer is assumes to be accurate to +/- 2km/h. At the end of the day he wants to know how far he has travelled, but unfortunately, he forgot to look at the distance indicator when he set out. He thinks that he drove for four hours, give or take a quartee of an hour. Estimate how far he travelled and assign an error to your result.5. A particle moves counterclockwise on a circular path of 400 ft radius. It starts from a fixed point which is horizontally to the right of the center of the path and moves so that s=1012 + 20t where s is the arc distance in feet and t is the time in sec. Compute the x and y components of acceleration at the end of 3 sec.
