what was the ball average speed during the time represented in the graph.
HINT; Divide rise/run
Distance/time
Question 2
2.
what was the ball average speed of the toy car during the two trials to the nearst tenth of m/s
HINT: Add all distances add all times then divide distance /time. then round your number
Question 3
3.
which cart will result in the greatest change in speed.
Question 4
4.
what was the average speed between the first 40 seconds.
HINT; Divide rise/run Distance/time
Question 5
5.
a bus travels 20 km in 30 min. what is average speed of the bus.
HINT: change your units from minutes to hours by dividing time by 60. then calculate speed.
Question 6
6.
based on the data in the table ,which object experienced the greatest force.
HINT: use F=ma triangle
Question 7
7.
Ablock is pulled 0.5 m to the right in 4.67 s.
what is the ball average speed to the nearst hundredth of m/s.
Question 8
8.
.A baseball player hits a baseball with a bat. The mass of the ball is 0.42 kg. The force of the bat hitting the ball is 30 N. What is the acceleration, to the nearest hundredth m/s2, of the baseball?
Hint :Use f=ma triangle to calculate you acceleration .
Question 9

Question 11
11.
which of the following match speed,velocity and acceleration?
Hint: Velocity is Speed+direction
Acceleration unit is m/s2
Question 12
12.
How much force is required to accelerate a 22 kg mass at 1.3 m/s2?
Question 13
13.
what is the ball average speed between 20 and 60 seconds.
Hint : the car stayed at the same distance Rise=0
Question 14
14.
what is the difference in speed of ball A and ball B ? round to the nearst tenth place.
HInt: Find speed A then Speed B then subtract the 2 numbers .
Question 15
15.
