A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its average acceleration?
22 - 4 / 3
A = 6 m/s 2

Find the acceleration then force
Tyler was walking to school at 2 m/s, then he looked at the time. He was late, so he starting running at 10 m/s. He got to school in 45 Seconds.
Tyler weighs about 800 kgs. What forces did he have playing on him while he was running to school?
A = 10 - 2 /45
A= 0.177 m/s2
F= 800 x 0.177
F= 141.6 N

Two part question!!!!
A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration ? Is this acceleration higher than that of a car which accelerates from 0 to 30 m/s in 8 seconds?
8-0 / 3 = 2.66 m/s2
30-0 / 8 = 3.75 m/s2

Find the acceleration of this image by using the force formula
F = M x A
45= 15 x A
45/15 = A
A= 3 m/s
