Answer:

Acceleration a =-1.75 m/s²

Explanation:

Given:

Initial speed u = 24 m/s

Final speed v = 10 m/s

Time taken t = 8 sec

Find:

Acceleration a

Computation:

a = (v-u)/t

a = (10-24)/8

a = -14 / 8

Acceleration a =-1.75 m/s²

Answer:

Accelaration =(v-u)/t

40-10/20m/s^2

30/20m/s^2

1.5m/s^2=accelaeration

V^2-u^2=2as

v=final velocity=unkown
u=initial velocity=0 m/s, because freely falling
a=acceleration due to gravity=9.8 m/s^2
s=distance (here height) traveled=4.5m

therefore the final velocity,
v^2=2*9.8*4.5
v=<span>9.39m/s</span>

A projectile is fired at ????0=355.0 m/s at an angle of theta=68.4∘ , with respect to the horizontal. Assume that air friction w

Deffense [45]

Answer:

Range will be 5707.364 m

Explanation:

We have given initial velocity of projectile u = 355 m/sec

Angle of projection = 68.4°

Acceleration due to gravity $g=9.81m/sec^2$

Horizontal range is given by $R=\frac{u^2sin2\Theta }{g}=\frac{355^2sin(2\times 68.4^{\circ})}{9.81}=8794.09m$

It is given that range is shorten by 35.1%

So range will be $8794.09-(8794.09\times \frac{35.1}{100})=5707.364m$
