Two children are pulling and pushing a 30.0 kg sled. The child pulling the sled is exerting a force of 12.0 N at a 45o angle. Th
e child pushing the sled is exerting a horizontal a force of 8.00 N. There is a force of friction of 5.00 N. What is the acceleration of the sled? Round the answer to the nearest hundredth

- initial velocity=u=80m/s
- Final velocity=v=18m/s
- Acceleration=a=-16m/s^2
- Time=t
We know
Answer:
0.90m/s²
Explanation:
Given parameters:
Initial speed = 6miles/hr
Final speed = 12miles/hr
Time taken = 3 seconds
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time. It is mathematically given as:
Acceleration =
We need to convert miles/hr to meters/seconds
Initial speed = 6 x x
x
= 2.68m/s
Final speed = 12 x = 5.37m/s
Acceleration = = 0.90m/s²
