Please use these equations to solve the problem: v=v0+at x=x0+v0t+1/2at2 Part A: A stone is thrown upwards from the edge of a cliff 18 m high. It just misses the cliff on the way down and hits the ground below with a speed of 18.8 m/s. (a) With what velocity was it released? (b) What is its maximum distance from the ground during its flight?
Please use these equations to solve the problem:
v=v0+at
x=x0+v0t+1/2at2
Part A:
A stone is thrown upwards from the edge of a cliff 18 m high. It just misses the cliff
on the way down and hits the ground below with a speed of 18.8 m/s. (a) With what velocity was
it released? (b) What is its maximum distance from the ground during its flight?
Part B:
A rocket is fired vertically upward with an initial velocity of 80 m/s. It accelerates
upward at 4 m/s2 until it reaches an altitude of 1000 m when its engines fail and it enters free fall.
(a) How long is the rocket in motion? (b) What is its maximum altitude? (c) What is its velocity
just before it crashes back into the earth?
Part C:
A car moving at a constant speed of 30 m/s suddenly stalls at the bottom of a hill.
The car undergoes a constant deceleration of 2 m/s2 while ascending the hill. (a) Write equations
for the position and velocity as functions of time, taking x = 0 at the bottom of the hill. (b) What
is the maximum distance travelled by the car after stalling? (c) Make graphs of x(t), v(t) and a(t).
