Answer:
i could be 3 but i think its 2
Explanation:
Answer: 350 newton
Explanation:
Force needed = ?
mass = 10kg
Acceleration = 35m/s2 (The SI unit of acceleration is metre per second square)
Recall that Force is the product of mass of an object and the acceleration by which it moves.
Force = mass x acceleration
Force = 10kg x 35m/s2
Force = 350N
Thus, the force needed is 350 newton
Answer:
ANGLE is 35.3 degree celcius
Explanation:
Given data:
mass m and 3m
initial speed Vi
particle with mass m is moving toward left while particle with mass 3m is moving toward right
By using conservation of momentum :
conservation of energy :
After collision, particle with mass m moves at right angles, thus by considering conservation of momentum in x & y direction,
x direction :
y direction :
subsitute these value in energy conservation
35.3 degree from x-axis
I think the answer its false i dont know how to explain that but it is false that what my teacher told me
