w#3 Forces-storr_ (37578) KS 3 28° Find the acceleration of the block. Answer in units of m/s2 010 (part 2 of 3) 10.0 points What is the block's speed when, starting from rest, it has traveled a distance of 2.35 m along the incline. Answer in units of m/s 011 (part 3 of 3) 10.0 points What is the magnitude of the perpendicular force that the block exerts on the surface of the plane at a distance of 2.35 m down the incline? Answer in units of N 012 10.0 points A block of mass m accelerates with accelera- tion g up a frictionless plane that is inclined at an angle o above tihe horizontal. The force Fo that pushes the block is at an angle 3 above the horizuatal. Find thes foce FExplanation / Answer

9)
mass , m = 3.86 kg
s = 2.35 m , theta = 28 degree
the accelration , a = net force/effective mass
a = ( m * g * sin(theta)) /m
a = 9.81 * sin(28) m/s^2
a = 4.61 m/s^2
10)
the final speed , v = sqrt(2*a*s)
v = sqrt(2*4.61*2.35) m/s
v = 4.65 m/s
11)
the magnitude of perpendicular force , N = m * g * cos(theta)
N = 3.86 * 9.81 * cos(28) N
N = 33.4 N
