Christine had p coins. then she found 87 more coins in a drawer. write an expression that shows how many coins christine has now.

type an asterisk ( * ) if you want to use a multiplication sign and a slash ( / ) if you want to use a division sign.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
