A truck covers 40.0 m in 8.50 s while smoothly slowing down to a final speed of 2.80 m/s. Find its acceleration in \({\rm{m}}/{{\rm{s}}^{\rm{2}}}\)

A body moving with uniform acceleration has a velocity of 12.0 cm/s in the positive x direction when its x coordinate is 3.00 cm. If its x coordinate 2.00 s later is -5.00 cm, what is the magnitude of its acceleration in \({\rm{cm}}/{{\rm{s}}^{\rm{2}}}\) ?

A particle moves along the x axis. Its position is given by the equation \(x = 2.00 + 3.00t + 4.00{t^2}\) with x in meters and t in seconds. Determine its position in m at the instant it changes direction

A particle moves along the x axis. Its position is given by the equation \(x = 2.00 + 3.00t + 4.00{t^2}\) with x in meters and t in seconds. Determine its velocity in m/s when it returns to the position it had at t = 0.

A drag racer starts her car from rest and accelerates at 10.0 \({\rm{m}}/{{\rm{s}}^{\rm{2}}}\) for the entire distance of 400 m . What is the speed of the race car in m/s at the end of the run?

A jet plane lands with a speed of 100 m/s and can accelerate at a maximum rate of -5.00 \({\rm{m}}/{{\rm{s}}^{\rm{2}}}\) as it comes to rest. From the instant the plane touches the runway, what is the minimum time in seconds before it can come to rest?

A truck on a straight road starts from rest, accelerating at 2.00 \({\rm{m}}/{{\rm{s}}^{\rm{2}}}\) until it reaches a speed of 20.0 m/s. Then the truck travels for 20.0 s at constant speed until the brakes are applied, stopping the truck in a uniform manner in an additional 5.00 s. How long in seconds is the truck in motion?

A truck on a straight road starts from rest, accelerating at 2.00 \({\rm{m}}/{{\rm{s}}^{\rm{2}}}\) until it reaches a speed of 20.0 m/s. Then the truck travels for 20.0 s at constant speed until the brakes are applied, stopping the truck in a uniform manner in an additional 5.00 s.
