Answer:
Lever => 
Pulley => G = M x n (gravitational acceleration)
Wheel and axle => M.A = Radius of the wheel/radius of the axle = R/r
Inclined plane => It can be divided into two components: Fi = Fg * sinθ - parallel to inclined plane. Fn = Fg * cosθ - perpendicular one.
Answer:
a) J = F t = 40 * .05 = 2 N-s
b) J = 2 N-s momentum changed by 2 N-s
c) Initial momentum appears to be zero
J = change in momentum = m v2 - m v1 = m v2 = 2 N-s
v2 = J / m = 2 / .057 = 35 m/s
d) if the impulse time was increased and the average force remained the same then the change in momentum would increase with a corresponding increase in velocity attained - note the increase in v2 in part c)
Answer:
these volcanoes are caused by the abundance of convergent plate boundaries around the Pacific, so D.
