- A cat falls from a tree (with zero initial velocity) at time t = 0. How far does the cat fall between t=0.3s and t = 1.4 s? Use Galileo's formula u(t) = 32t fus. Answer: ft.A family drives on a trip to visit their relatives. On the first day they travel 550 miles with an average speed of 50 mi/hr, on the second day 420 miles with an average speed of 35 mi/hr and on the third day 585 miles with an average speed of 45 mi/hr. a) What is the total driving time? b) What is the average speed for the trip?The x component of the velocity of an object moving along the x axis is given as vy = 4t – 3t where vy is in meters per sec and t in seconds. The x component of its average velocity over the interval of time from t =0 to t= 2 sec is: O -2m/s O 2 m/s O -4m/s
- A boy runs for 23 seconds. During the first 10 seconds, his minimum speed is 2.2 m/s, while his maximum speed is 3.1 m/s. During the remaining time, his minimum speed is 3.1 m/s, while his maximum speed is 4.7 m/s. calculate the maximum (least upper bound) on the distance that he runs, in meters.Piolo's car is traveling initially at 20k(m)/(h). What is its final velocity if he accelerates the car to 3.3k(m)/(h^(2)) for 3h ?The velocity of a particle traveling in a straight line is given by v = (6t – 3t²) m/s, where t is in seconds. If s = 0 when t = 0, determine the particle's deceleration and position when t = 5 s. How far has the particle traveled during the t = 5 s time interval, and what is its average speed?
