So what will be the equation if the force is acting horizontal?

50 - 4.0*9.8*sin(30)-4.0*0.7*9.8*cos(30) = 50 - 23.76 = 26.64 26.64/4.00 = 6.56 m/s^2

Homework Statement a 4.00-kg block is sliding up the plane on a 30 degree incline. If the coefficient of kinetic friction between the block and the inline is .700. What will be the acceleration of the block if a 50-N horizontal force pushes on the block? Homework Equations 50 - mgsin(30) -...

v = sqrt (Vi^2 + 2*g*h) v = sqrt( 20^2 + 2*9.8*10) v = 24.4 m/s ?

So is it v=sqrt(2*9.8*10) +20 so V = 14 m/s + 20 m/s v = 24 m/s?

Homework Statement A ball is thrown from the edge of a 10.0 m high cliff with a speed of 20.0 m/s at an angle of 30 degrees below horizontal. What is the speed of the ball when its hits the ground below the cliff? Options : 1) 26.3 m/s 2) 28.1 m/s 3) 31.4 m/s 4) 24.4 m/s 5) 29.5 m/s I am new...
