Can someone help me with a physics problem?

Consider a stone with mass, m, thrown straight upwards with speed v = 1 m/s, from a height of 10 m. Assume ground corresponds to a height, h = 0 m, and define upwards to be the positive direction
a) What is the initial velocity of the stone?
b) What is the maximum height reached by the stone (assume acceleration due to gravity has a magnitude of 9.8 m/s2)?
c) Once the stone hits the ground, what will have been its total displacement?
d) What is the velocity when the stone hits the ground?

Here are my answers, I don't know if they are correct.

a) +1 m/s
b) 10.05 m
c) -10 m
d) 14.04 m/s

Are my answers right?

Without going thru each calculation myself, they all look ok
