The initial speed of a body is 3.28 m/s. What is its speed after 2.32 s if it accelerates

Helga [31]

Final velocity = initial velocity + acceleration * time

v = u + at

v = 3.28 + 2.32 * 2.08

v = 3.28 + 4.83

<u>v = 8.11 m/s</u>

A projectile is fired horizontally from a gun that is 54.0 m above flat ground, emerging from the gun with a speed of 330 m/s. (

krok68 [10]

Explanation:

Given

height of building (h)=54 m

Projectile velocity=330 m/s

initial vertical velocity $(u_y)=0$

Initial horizontal velocity $(u_x)=330 m/s$

Time taken to cover vertical height of 54 m

$h=ut+\frac{gt^2}{2}$

$54=0+\frac{9.81\cdot t^2}{2}$

$t=\sqrt{\frac{54\times 2}{9.81}}$

t=3.31 s

Horizontal distance traveled in this time

$R_x=u_x\times t$

$R_x=330\times 3.31=1094.94 m$

Vertical component of velocity when it hits the ground

v=u+at

$v=0+9.81\times 3.31=32.47 m/s$
