A `5 kg` block is projected upwards with an initial speed of `10 ms^(-1)` from the bottom of a plane inclined at `30^(@)` with horizontal . The coefficient of kinetic friction between the block and the plane is `0.2`
a. How far does the block move up the plane ?
b. How long does it move up the plate ?
c. After time from its projection does the block again come to the bottom ? What speed does it arrive?
