Human Chess
Rules
1. Spread yourselves around the room2. First to get to an answer puts their hand up3. I wait for first 3 hands4. If the first person is correct they roll a die which
determines how many steps they can take. On their ‘walk’ they can eliminate anyone by touching them on the arm.
5. Last man/woman standing!6. BUT… If you have been eliminated and answer a
question correctly, you’re back in the game.
Question 1
A stone is projected vertically upwards so that its position above the ground level after t seconds is given by:
s(t) = 98t-4.9t2
Find the velocity and acceleration functions for the stone and find the initial position and velocity for the stone.
Question 1
A stone is projected vertically upwards so that its position above the ground level after t seconds is given by:
s(t) = 98t-4.9t2
Find the maximum height reached by the stone
Question 1
A stone is projected vertically upwards so that its position above the ground level after t seconds is given by:
s(t) = 98t-4.9t2
Find the time taken for the stone to hit the ground
Question 2
The height (cm) of a certain species of shrub t years after it was planted is given by:
H(t) = 20 ln (3t + 2) + 30
How high was the shrub when it was planted?
Question 2
The height (cm) of a certain species of shrub t years after it was planted is given by:
H(t) = 20 ln (3t + 2) + 30
How long did it take for the plant to reach a height of 1m?
Question 2
The height (cm) of a certain species of shrub t years after it was planted is given by:
H(t) = 20 ln (3t + 2) + 30
At what rate is the shrub’s height changing 3 years after being planted?
Question 3
A body moves along the x-axis with the displacement function:
x(t) = 100 (2 – e-t/10) where x is in cm
Find the acceleration function
Question 3
A body moves along the x-axis with the displacement function:
x(t) = 100 (2 – e-t/10) where x is in cm
Find the initial velocity and acceleration of the body
Question 3
A body moves along the x-axis with the displacement function:
x(t) = 100 (2 – e-t/10) where x is in cm
Find t when x = 150 cm
Question 4
A particle, P, moves in a straight line so that its displacement from the origin (cm) is given by:
s(t) = 100t + 200e-t/5
Where t is the time in seconds.
Find when the velocity of P is 80 cm/s
