A car is decelerated to 20 m/s in 6 seconds A car is decelerated to 20 m/s in 6 seconds. Given that it travels a distance of 240 m, calculate its: initial velocity, b) deceleration.

A cheetah can reach a speed of 80 km/h from rest in just 3 seconds. Change 80 km/h to m/s. b) Calculate: i) its acceleration, ii) the distance it travels, iii) its average speed.

A train moving at 20 m/s increases its speed to 35 m/s while accelerating at 3 m/s2. Calculate the: time interval during which it accelerates, b) distance travelled by the train.
