Sagot :
A) t=?
h = v1(y direction) *t +1/2 g*tt
78.4=0 *t + 1/2*9.8*tt
78.4 = 0+ 4.9 tt
tt=t(squqre) =78.4/4.9 =16
so t = sqrt16 =4 sec. the time needed to hit the ground.
B) how far =x =?
x =v(horizontal) *t =5*4 =20 m.
h = v1(y direction) *t +1/2 g*tt
78.4=0 *t + 1/2*9.8*tt
78.4 = 0+ 4.9 tt
tt=t(squqre) =78.4/4.9 =16
so t = sqrt16 =4 sec. the time needed to hit the ground.
B) how far =x =?
x =v(horizontal) *t =5*4 =20 m.
a) It will take 4 seconds to reach the bottom of the cliff
b) The stone strike at a distance of 20 m from the bottom of the cliff
What is equation of motion?
It is an equation that describe the behavior of a physical system in terms of its motion as a function of time
using equation of motion
since, it is thrown initial horizontally at a speed of = 5m/s
initial vertical velocity = 0
s = u t + 1/2g(t^2)
78.4 = 1/2 * 9.8 * (t^2)
t^2 = (78.4 *2)/9.8
t = (16)^(1/2)
t= 4sec
a) It will take 4 seconds to reach the bottom of the cliff
b) distance from the base of cliff stone strike = horizontal velocity * time
5 m/s * 4 second
20 m
hence , the stone strike at a distance of 20 m from the bottom of the cliff
