A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of 10.0 m/s. the cliff is 50.0 m above a flat horizontal beach. (a) how long after being released does the stone strike the beach before the cliff? (b) find the speed just before the stone strikes the beach. (c) find the traveling horizontal distance for the stone

Solutions

Expert Solution

A projectile motion is combinatrion of horizontal and vertical motion taking place simultaniously ......

whose both components are independent of each other...........  

(a)

as vertical component of initial velocity is zero at start equation of motion followed for vertical part of motion will be ......

................. as object is thrown horizintally

m

h = 0 (on ground)

so the equation after putting values bacomes ......

time correspomndindg to object reaching ground wil be

(b)

since acceleration in horizontal direction is always zero......... speed in that direfction could have not changed during entire motion i.e

as initial velocity of object was zero in vertical direction and a constant acceleration was acting on it for time period of t

(c)

horizintal distance travelled = constant horizontal velocity time of flight
