<span>a.
the force in the direction of movement
Fx = F x cosA*
Fx = 12 x cos25*
Fx = 10.88
m x a = 10.88
a = 10.88/5
a= 2.18 m/s^2
b.
when the block will be lifted off the floor and when the vertical component
Fy = mg
Fy = F x sin25*
Fy= 5 x 9.8
Fy= 115.94 N
c.
if Fx = ma
a = 115.94/5
a= 23.19 m/s^2
hope it helps

Answer:
im pretty sure the answer is c please mark me brainliest
Answer:
0.34 s
Explanation:
Given that,
Initial speed of a ball, u = 5.8 m/s
It is kicked at an angle of 17.0° above the horizontal.
The vertical component of velocity will be,
Let it takes t time in the air before it lands on the ground again. It can calculated as :
So, it will take 0.34 seconds.
Answer:
Gamma rays occupy the short-wavelength end of the spectrum; they can have wavelengths smaller than the nucleus of an atom. Visible light wavesare one-thousandths the width of human hair--about a million times longer than gamma rays. Radio waves, at the long-wavelength end of the spectrum, can be many meters long.
