The correct answer would be 1.375 < t < 3 i hope this helps anyone
Answer:
Explanation:
Using the conservation of the linear momentum P:
so:
where 
is the mass of kevin, 
is the velocity of kevin before he grabs her brother, 
is the velocity of her brother and him after grabs her brother and 
is the velocity of both after the collition.
So, replacing the values and solving for Vk, we get:
Answer:
1. a) Draw a line towards the right side from the engine
b) This force pushes the boat forward and helps it accelerate further
2. a) Fixed volume for both solid and liquid
Compressible for only solid
Fixed shape is also for only Solid
b) The answer is 'c'
c) Solids, because they have their particles closely packed therefore they can be compressed (not so sure bout this answer)

Given:
Mass of body = 30 kg
gravitational acceleration on the moon = 1.62 m/s
2
Weight of the body on the moon = Mass of the body×gravitational acceleration on the moon=30×1.62=48 N
