You throw a stone horizontally at a speed of 5.0 m/s from the top of a cliff that is 78.4 m high.
Monica [59]

a)You throw a stone horizontally at a speed of 5.0 m/s from the top of a cliff that is 78.4 m high.

from above statement we got

height = 78.4 m

since the ball is thrown, so its vertical velocity would be zero

u = 0

taking g = 9.8m/s^2

now, using the equation of motion

h = ut + gt^2/2

now putting all the values in it

we got ,

78.4 = 9.8 * t^2/ 2

by solving we got,

t = 4 sec

b) now, since along the horizontal , no force acting and accelaration is zero so

R = ut , R is RANGE

R = 5 * 4

range =  20 m

c)  vertical components of the stone’s velocity just before it hits the ground = v sin θ =

horizontal   components of the stone’s velocity  just before it hits the ground = v cos θ

A plane starting from rest accelerates at 3m/s2 for 25s. Calculate the increase in velocity after:
horsena [70]
  • Initial velocity=u=0m/s
  • Acceleration=a=3m/s^2

Time not needed now

Case-1:-

  • Time=1s
  • Final velocity=v

\\ \rm\hookrightarrow v=u+at

\\ \rm\hookrightarrow v=0+3(1)

\\ \rm\hookrightarrow v=3m/s

Case-2:-

  • Time=3s

\\ \rm\hookrightarrow v=0+3(3)

\\ \rm\hookrightarrow v=9m/s

Case-3:-

  • Time=25s

\\ \rm\hookrightarrow v=0+3(25)

\\ \rm\hookrightarrow v=75m/s

A piston in a gas supply pump has an
KonstantinChe [14]

Answer:

A. 60 Joule

Explanation:

First find the force given the pressure and area.

F = AP

F = 500 cm² × (1 m / 100 cm)² × 4000 N/m²

F = 200 N

Now find the work:

W = Fd

W = 200 N × 30 cm × (1 m / 100 cm)

W = 60 J
