Worksheet Kinematics 1. A body starts from rest and reaches a speed of 5 m/s after travelling with uniform acceleration in a straight line for 2 s. Calculate the acceleration of the body.

2. A body starts from rest and moves with uniform acceleration of 2m/s2 in a straight line.
a. Calculate the velocity after 5s.
b. Calculate the distance travelled in 5s.
c. Find the time taken for the body to reach 100m from its starting point.

3. An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.

Determine the skidding distance of the car (assume uniform acceleration). 12. A kangaroo is capable of jumping to a height of 2.62 m. Determine the takeoff speed of the kangaroo. 13. If Michael Jordan has a vertical leap of 1.29 m, then what is his takeoff speed and his hang time (total time to move upwards to the peak and then return to the ground)? 14. A bullet leaves a rifle with a muzzle velocity of 521 m/s. While accelerating through the barrel of the rifle, the bullet moves a distance of 0.840 m. Determine the acceleration of the bullet (assume a uniform acceleration). 15. A baseball is popped straight up into the air and has a hang-time of 6.25 s. Determine the height to which the ball rises before it reaches its peak. (Hint: the time to rise to the peak is one-half the total hang-time.) 16. The observation deck of tall skyscraper 370 m above the street. Determine the time required for a penny to free fall from the deck to the street below. 17. A bullet is moving at a speed of 367 m/s when it embeds into a lump of moist clay. The bullet penetrates for a distance of 0.0621 m. Determine the acceleration of the bullet while moving into the clay. (Assume a uniform acceleration.) 18. A stone is dropped into a deep well and is heard to hit the water 3.41 s after being dropped. Determine the depth of the well. 19. It was once recorded that a Jaguar left skid marks
