1. Plot a velocity-time graph using table:
Draw a line of the best fit and use your graph to find:
° Acceleration during the first 4 seconds
° The distance traveled in the first 4 seconds;
The distance traveled in the first 5 seconds;
The average speed during the 8 seconds of motion shown.
2. The diagram below shows a block of wood on a sloping surface. Copy the
diagram and label all the forces that act on the block of wood.
3. A spring stretches from 10 cm to 22 cm when a force of 4 N is applied. If it
obeys Hooke’s law, find its total length in cm when a force of 6 N is applied.
4. A rocket has a mass of 500 kg.
What is its weight on Earth, if g = 10 N/kg?
At lift-off the rocket engine exerts an upward force of 25 000 N. What is the
resultant force on the rocket?
What is its initial acceleration?
5. A ball is projected vertically upwards with an initial velocity of 30 m/s. Find its
maximum height and the time taken to return to its starting point. Neglect air
resistance and take g = 10 m/s2
.(Hint: the velocity of the ball is zero at its highest point.)
