An automobile travels at the rate of 25 m/s for 5 mins, then 30 m/s for 10 mins, and finally at 10 m/s for 2 mins. Find a) the total distance covered in meters and b)the average speed in m/s.

A body with initial speed 12 m/s moves with a constant acceleration and travels 500 m in 30 s. Find a) the average velocity, b) the final velocity, and c)the acceleration.

A ball is thrown vertically downward with the initial velocity of 14 m/s from a height of 60 m. Find the speed with which it strikes the ground and its time of fall.

A box dropped from a balloon reaches the ground in 20 s. Determine the height of the balloon and the speed with which it hits the ground.

Compute the least acceleration with which a man of mass 75 kg can slide down a rope which can sustain weight of 580 N.

7,500+180,000+1,200=188,700m (total distance)

188,700÷3=62,900 (average)
