Yesterday you walked 20 meters to the right from your house to the bus stop, which took you 20 seconds. You waited at the bus stop for 1 minute before realizing you forgot your Mathematics homework at home. You ran back to your house in 5 seconds. It took you 10 seconds to find your homework, and then you ran back to the bus stop in 5 seconds just in time to catch the bus. What was your average velocity for the entire period of motion?

Ahmed and Khalid are having a 100m race from start to finish. Ahmed gives Khalid a 25m head start (he waits until Khalid is 25m away before starting) .Khalid travels at a constant velocity of 5 m/s. Assuming that Ahmed accelerates uniformly from rest at 0.75 m/s2, does he pass Khalid before the finish line? If so, where? If not, how much longer does Khalid take to finish? (explain your reasoning)
An advertisement for the newest model of a Mercedes sports claims the car can go from 0 to 60 miles per hour (mph) in just 3.3 seconds! a) How many meters per second (m/s) is 60 mph? b) In m/s 2 (sometimes written as m/s/s also, just so you know), what is the supposed acceleration of the sports car? c) Impressed by this claim, Sherry buys one. She hops into her new Mercedes sports car and steps on the gas. She’s an engineer and did the math later on; she discovered that her car’s acceleration is 6.7 m/s2 . i) Is her car’s acceleration faster or slower than the advertisement claims it should be? ii) In seconds, how long did it actually take for Sherry’s car to reach 60 mph
A ball rolls along flat ground at 7.5 m/s (call this the positive direction) then encounters a hill. If the ball rolls 19 m up the hill before coming to a stop, what was the acceleration (in m/s2) experienced by the ball as it rolled up the hill?
a) A car moving with a constant velocity travels 360 meters in 9 seconds. What was the average velocity of the car in m/s? b) A second car starts from rest, speeds up with constant acceleration, and travels 360 meters in 9 seconds. What was the average velocity of the second car in m/s? c) What was the final velocity of the second car (in m/s)?

A child on a sled moving at 5 m/s, reaches the bottom of the hill and simply glides along, slowing to a reduced speed of 3 m/s after gliding for 16 m. What is the magnitude of their acceleration (in m/s2) as they slow, rounded to one decimal place?
A train starts from rest and accelerates uniformly, until it has traveled 5.6 km and acquired a velocity of 42 ms. The train then moves at a constant velocity of 42 m/s for 420 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The acceleration during the first 5.6 km of travel is closest to: O 0.20 m/s² O 0.14 m/s² O 0.19 m/s² 0.17 m/s² O 0.16 m/s²
A cheetah can accelerate from rest to a speed of 25.5 m/s in 5.00 s. What is its acceleration (in m/s2)? (Enter a number.)
