Answer:
First Car Avg: Velocity=0.11 m/s
Second Car Avg: Velocity=0.28 m/s
Explanation:
Data
D1 (First Car Displacement)=0.25m
T1 (First Car total time taken)=2.23s
D2 (Second Car Displacement)=0.25m
T2(Second Car time taken)=3.13-2.23=0.9s
Avg: Velocity1=?
Avg: Velocity2=?
Solution
Avg: Velocity1=D1/T1
Avg: Velocity1=0.25/2.23
Avg: Velocity1=0.11 m/s
Avg: Velocity2=D2/T2
Avg: Velocity2=0.25/0.9
Avg: Velocity2=0.28 m/s
There are two forces acting on a rocket at the moment of lift off: Thrust pushes the rocket upwards by pushing gases downwards in the opposite direction.Weight is the force due to gravity pulling the rocket downwards towards the centre of the earth.So I'm thinking the answer is THRUST.
