Time before projectile hits wall
= 88.2 m / 29.4 m/s = 3 seconds
Vertical velocity of projectile after three seconds
= 3*9.8 = 29.4 m/s
Horizontal velocity of projectile after three seconds, assuming no air resistance
= 29.4 m/s (given)
Conclusion:
velocity of projectile when it hits the wall
= < 29.4, -29.4> m/s
= sqrt(29.4^2+29.4^2) m/s east-bound at 45 degrees below horizontal
= 41.58 m/s east-bound at 45 degrees below horizontal.
A: 53.1
Inverse tan of the opposite side (y=4) divided by the adjacent side (x=3) gives:
The angle of the resulting vector is 53.1 degrees subtended from the x axis.
Answer:
B. A material is classified as a semiconductor if its resistance to the flow of electric current is too low to permit it to be called a conductor.
Explanation:
A material is classified as a semiconductor if its resistance to the flow of electric current is too low to permit it to be called a conductor is true of semiconductors.
Point the muzzle in a safe direction.
Answer:
Acceleration,10
Explanation:
First 4kg is your mass,
Second 40N is your force
,so you need your acceleration
The answer is 10 because
F=40N
M=4kg
A=10
You divide 40 out of 4 and you get 10
