Equations of motion & projectiles

1)    If a car starts from rest and accelerates at ms-2 for seconds – what is its final velocity?

ms-1

2)    What distance does a bus travel if it accelerates from a speed of m/s to m/s in seconds?

m

3)    What is the final velocity of a bus if it accelerates from m/s for m with an acceleration of ms-2?

ms-1

4)    Calculate the distance travelled by a falling sandwich if it falls out of an office window for s. (Take g=10ms-2)

m

5)    Calculate the time taken for a ball of mass kg to land again after being thrown vertically upwards with an initial velocity of m/s. (Take g=10ms-2)

s

6)    Calculate the maximum height of a ball of mass kg if it is thrown vertically upwards with an initial velocity of m/s. (Take g=10ms-2)

m

7)    A ball is thrown vertically upwards. It reaches a velocity of m/s at a height of m. Taking g=10ms-2 calculate the initial velocity of the ball.

ms-1

8)    A ball is projected horizontally off a cliff with a velocity of m/s. Calculate the time taken to hit the ground m below. (Take g=9.8ms-2)

s

9)    If a ball is projected horizontally off a cliff with a velocity of m/s and hits the ground m below – calculate how far away it lands from the foot of the cliff. (Take g=9.8ms-2)

m

10)  A ball is fired from sea level at an angle of 30 degrees to the horizontal with a velocity of  20m/s. Calculate the distance it travels over the horizontal before landing. (Take g=9.81ms-2)

m
