A wood block is sliding up a wood ramp. if the ramp is very steep, the block will reverse direction at its highest point and sli
DanielleElmas [232]
<span>Answer: So it gets to the top of the ramp and stops. The parallel force pushing it down the ramp is mg sin θ, but for it to move, the frictional force must be overcome. This frictional force is μmg cos θ, where μ is the coefficient of static friction. For movement, then, mg sin θ > μmg cos θ ==> tan θ > μ ==> θ > arctan 0.5 = 26.565° ==> θ = 27°</span>

A race car accelerates at a constant rate from 20 m/s to 60 m/s in a time of 2 seconds. What is the car’s acceleration?
Vlada [557]

\huge\fbox{Answer ☘}

Given ,

initial velocity , u = 20 m/s

final velocity , v = 60 m/s

time taken = 2 seconds

Now ,

\bold{acceleration =  \frac{v - u}{t} } \\ \\   =  > \bold{ \frac{60 - 20}{2} }  \\ \\  =  >  \bold{\frac{40}{2} } \\  \\ \bold{ => 20 \: ms {}^{ - 2}}

hope helpful~
