Answer:
<u>According </u><u>to</u><u> the</u><u> </u><u>Given</u><u> Statement</u><u> </u>
Canon fires directly upwarda at 150m/s ( Initial speed, u )
Acceleration due to gravity is 10m/s²
Since Cannon ball reach it maximum height so its final velocity v will be 0 m/s .
Using Kinematic Equation
On substituting the value we get
➥ 0 = 150 + 10 × t
➥ 150 = 10 × t
➥ 150/10 = t
➥ 15 s = t
So, it will take 15 seconds .
Answer:
for 8th one it is 33.4k joules and for ninth one i think 95degree C.
Explanation:
hope this helps
thank you.
More suvat equations here, this time s=ut+1/2at^2 where s is the displacement, t is the time, and a is the acceleration.
So s=0*20+1/2*9.81*20^2
simplified: s=1/2*9.81*(20)^2
s=1962
The height of the cliff is 1962m
I got the same answer as above. So she is correct.
Answer
Thus, the earth has three types of motion at the same time i.e. circular motion, periodic motion and rotational motion. ... So, the wheel of a sewing machine shows rotational motion. The sewing machine has also a needle which moves up and down continuously (as log as the wheel rotates).
Sorry if you get this wrong but I believe it’s C because without inertia.. particles will fall apart because inertia keeps everything together in the same motion
