A runner covers the last straigjt stretch of a race in 4 s. during that time, he speeds up from 5m/s to 9m/s.

a bus is moving with a constant velocity 10m/s along horizontal rode. a man standing inside bus throws ball virtically upward with valocity 8 m/sec WRT tohimself and cathes the ball. the magnitude of displacment of ball WTR ground will be

A two-stage rocket is traveling at 1210m/s with respect to the earth when the first stage runs out of fuel. Explosive bolts release the first stage and push it backward with a speed of 40m/s relative to the second stage after the explosion.

A cheetah has an acceleration that has x and y components of ax = 5.3 m/s2 and ay = 3.8 m/s2. the cheetah's mass is 61 kg. find the net force acting on the cheetah.

the acceleration of gravity is 28 times on sun than earth. Imagine there is a space suit that let you stand on sun. Calculate the weight of 100 kg person on earth in newtons

A force of 20 n acts upon a 5 kg block, calculate acceleration of the object
