Motion on an Inclined Plane – Practice
1) A mass of 6.5kg is on an inclined plane at an angle of 20° to the horizontal.
a) the weight of the object:
b) the normal force acting on the object:
c) the weight component acting parallel to the surface of the inclined plane:
2) An object of 25kg mass sits on an inclined plane at an angle of 42° to the horizontal. Calculate the acceleration of the object:
1) a) 63.7N b) 59.9N c) 21.8N
2) 6.6 m/s2
