Kinematics: solved problems
Uniform and uniformly accelerated motion: distance, speed, acceleration.
A body accelerates from rest at 2 m/s² — what distance does it cover in 5 s?A body starts moving from rest with constant acceleration a = 2 m/s². What distance will it cover in t = 5 s?grades 9–10A stone falls freely for 3 seconds — from what height does it fall, and at what speed does it land?A stone falls freely with no initial speed for t = 3 s. Find the height of the fall and the speed at the moment of impact. The acceleration due to gravity is g = 10 m/s².grades 9–10A car drove half the distance at 60 km/h and the rest at 40 km/h. Average speed?A car drove the first half of the DISTANCE at 60 km/h, and the second half of the distance at 40 km/h. Find the average speed over the whole distance.grades 9–11
