Motion Basics Physics 2

The car starts from rest and accelerates uniformly to reach a maximum speed of 69.44 ms^-1 in 3.8 s. What is the acceleration of the car?

• 9.3 ms^-2

• 18.3 ms^-2

• 24.43 ms^-2

• 20 ms^-2

Starting from rest, accelerating uniformly at 15 ms^-2 to 76 ms^-1 in 5 seconds. Calculate the distance the car would travel.

• 90 m

• 187.5 m

• 25.3 m

• 75 m

Julia is landing her plane she touches down at one end and decelerates at 8.0 ms^-2 for 15 seconds before coming to a stop. How fast was she moving when she touched down?

• 80 ms^-1

• 120 ms^-1

• 880 ms^-1

• 150 ms^-1

Julia is landing her plane she touches down at one end of the runway at 130 ms^-1 and decelerates at 8.0 ms^-2 for 15 seconds before coming to a stop. How far has she travelled along the runway before she stopped?

• 1050 m

• 1300 m

• 2850 m

• 285 m

A crossroads is 15m wide. A bus of length 8.0m is travelling along the intersection at a steady speed of 28ms^-1. How long does the bus take to completely clear the intersection?

• 0.82 s

• 0.54 s

• 4.3 s

• 1.32 s

The bus is moving at 28ms^-1. The driver sees a dog 100m away. The driver has a reaction time of 0.80s before he applies the brakes. Calculate the time the bus takes to stop just in front of the dog from the breaks being applied.

• 2.5 s

• 3.53 s

• 7.14 s

• 5.54 s

Darth is walking at 4.5 ms^-1 when Yoda steels his ice cream. It takes Darth 35 s to catch up to Yoda 600 m away. What was Darth's final speed!

• Who cares he is using the force!!!!

• 400 ms^-1

• 62.45 ms^-1

• 29.7 ms^-1

Darth is moving at 3 ms^-1 . He accelerates covering 300 m in 0.25 s. His mass is 100 kg. Calculate the net force causing his acceleration.

• 598.5 N

• 5985000 N

• 9576 N

• 9576000 N

Yoda (35 kg) uses a net force of 1928.5 N to move from sitting down to a speed of 500 ms^-1 to reach KFC before they close. Calculate the distance he covers doing this.

• 3765 m

• 46000 m

• 2268.4 m

• 3500.32 m

Yoda is eating KFC while walking at 3.21ms^-1 he accelerates to 90ms^-1 trying to avoid Luke over 45m. Calculate his acceleration.

• 30.43 ms^-2

• 45.45 ms^-2

• 89.99 ms^-2

• 120 ms^-2
