Answer:
Your average speed is 60 kilometers per hour
Explanation:
240 divided by 4 is 60
240/4=60
Momentum = Mass*Velocity
Momentum = 75*13
Momentum = 975
The answer is 975 kg-m/s
Hope you get help
Answer:
Sorry this isn’t going to be any help. You don’t have any statement that I’m able to see.
Explanation:
Answer:B
Explanation: I think this is the answer
Answer:
0.81 m/s^2
Explanation:
A child rides a bicycle from rest
The child reaches a velocity of 3.8m/s
The time is 4.7 secs
Therefore the acceleration can be calculated as follows
v= u + at
3.8= 0 + a(4.7)
3.8= 0 + 4.7a
3.8-0= 4.7a
3.8= 4.7a
a= 3.8/4.7
= 0.81 m/s^2
Hence the acceleration is 0.81 m/s^2
