I think you're asking what his 'ke' will be. Does that mean his 'kinetic energy' ? Well, that'll just be
<em>ke = (1/2) x (his mass) x (his speed when he touches down)²</em>
I believe it would be x because you are trying to find the width of the wave but i could be wrong
Answer:
Explanation:
Time of flight is the time taken by the bulet in air. Time of flight is expressed as T = Usinθ/g where;
U is the initial velocity = 180m/s
θ is the angle of launch = 90° (Since the bullet is shot upwards)
g is the acceleration due to gravity = 9.81m/s²
T = 180sin90/9.81
T = 180/9.81
T = 18.35s
<em>Hence the bullet will spend 18.35s in air</em>
<em></em>
The height covered by the bullet is the maximum height. Maximum height is expressed as;
H = u²sin²θ/2g
H = 180²sin²90/2(9.81)
H = 180/19.62
H = 9.17m
<em>Hence the bullet will go 9.17m high</em>
Because the gravity pulls use towards the ground and our bones can’t take the amount of weight hitting the surface
Answer:
False
Explanation:
Something with high specific heat cooling down would take longer to heat up.
