How many meters are in a kilometer

Convert 115 km/h into m/s.

4. Convert 39 m/s into km/h.

A car manufacturer claims that its latest model can

go from “0 to 90” in 7.5 seconds. If “90” refers to

90 km/h, calculate the car’s acceleration?

Mars’ gravitational force is less than that of Earth’s . If an astronaut drops a hammer and its speed increases from 0 to 15 m/s in 4.04 s, what is the acceleration due to gravity on Mars?

A fighter jet landing on an aircraft carrier’s flight deck that has a length of 300 m must reduce speed from about 153 km/h to exactly 0 km/h in 2 s. What is the jet’s acceleration?

A child sleds down a steep, snow-covered hill with

an acceleration of 2.82 m/s². If her initial speed

is 0 m/s and her final speed is 15.5 m/s, how long

does it take her to reach the bottom of the hill?

Once the child in the previous problem reaches the

bottom of the hill, she continues to slide along the flat, snow-covered ground until she comes to a stop. If her acceleration is -0.392 m/s², how long does it take her to travel from the bottom of the hill to her stopping point?

The Formula Rossa at Ferrari World Amusement Park has an acceleration of 13.89 m/s². How long does it take for it to reach its top speed of 240 km/h?

A bicyclist accelerates at 0.89 m/s² during a 5 second interval. If his initial speed was 9.2 m/s, what is his final speed?

An automobile accelerates 1.77 m/s² over 6 seconds to reach freeway speed at the end of the ramp. If the car’s final speed is 88 km/h, what was its initial speed, in km/h, when it began accelerating.
