A horizontal force of 73 N pushes a 7 kg block up a frictionless incline that makes an angle of 20° with the horizontal.
(a) What is the normal force that the incline exerts on the block?
64.5N
from cos(20)*68.67
(b) What is the acceleration of the block? (Hint: assume up the block as the positive direction.)
3.35m/s2
from sin(20)*68.67 = 23.48
F = MA
23.48/7 = 3.35
