Answer:
4.90m/s²
Explanation:
According newton's second law of motion
Summation of forces along the plane Fm = mass × acceleration
The force acting down the plane is the moving force Fm
Fm = Wsin(theta)
W is the weight of the object
Substituting in the formula of newton's second law we have;
Fm = ma...... *
Fm = Wsin theta
Fm = 562sin30°
Fm = 562(0.5)
Fm = 281N
Get the mass
W = mg
m = W/g
m = 562/9.8
m = 57.3kg
From equation *
Fm = ma
a = Fm/m
a = 281/57.3
a = 4.90m/s²
Hence the acceleration of the trunk is 4.90m/s²
