Answer:
An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. ... A net force = unbalanced force. If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.
Explanation:
Answer:
Amplitude
Explanation:
The amplitude of a periodic variable is a measure of its change over a single period. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values. In older texts the phase is sometimes called the amplitude.
Answer:
1027.2 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 32.2 ft/s


The height the tomato would fall is 450+577.2 = 1027.2 m
Explanation:
It is given that,
Velocity of particle 1, u₁ = 10 m/s
Velocity of particle 2, u₂ = 5 m/s
Let v₁ and v₂ are the final speed of both particles after the collision. Applying the conservation of momentum as :

......................(1)
For an elastic collision, the coefficient of restitution is equal to 1 as :


................(2)
On solving equation (1) and (2), we get,


So, the speeds of particle 1 and particle 2 after the collision is 5 m/s and 10 m/s respectively. Hence, this is the required solution.
