Answer:
0.182 m/s
Explanation:
m1 = 30,000 kg, m2 = 110,000 kg, u1 = 0.85 m/s
let the velocity of loaded freight car is v
Use the conservation of momentum
m1 x u1 + m2 x 0 = (m1 + m2) x v
30,000 x 0.85 = (30,000 + 110,000) x v
v = 0.182 m/s
We Know, F = m*a
Here, F = 10 N
m = 1 Kg
Substitute their values in the equation,
10 = 1 * a
a = 10/1
a = 10
So, your final answer & the acceleration of the object would be 10 m/s²
Hope this helps!
lake effect snow is the correct answer
A kangaroo will stay 0.699s in the air when he jumps.
<h3>What motion does the projectile make?</h3>
A projectile is an object that is launched vertically into the air and moves while being pulled by gravity. A projectile is an object that is launched into the air horizontally and moves regardless of gravity.
<h3>How do you determine the rate of descent?</h3>
G = -9.81 m/s2 is the acceleration of gravity close to the earth. Simply multiply the acceleration of gravity by the period since the object was released to determine the object's speed (or velocity). In other words, velocity is equal to -9.81 m/s2 * time, or V = gt.
<h3>According to the given information:</h3>
From the conversion of energy =
t = √(2h/g)
= √((2 x 2.40) / 9.8)
=0.699 s
A kangaroo will stay 0.699s in the air when he jumps.
