Answer:
Explanation:
As we know that initial speed of the crate is
now finally the crate will come to rest
so we have
now the deceleration due to frictional force is given as
distance moved by the crate before it will stop is given as
so we will have
A :-) for this question , we should apply
F = ma
( i ) Given - m = 2 kg
a = 15 m/s^2
Solution :
F = ma
F = 2 x 15
F = 30 N
( ii ) Given - m = 2 kg
a = 10 m/s^2
Solution :
F = ma
F = 2 x 10
F = 20 N
.:. The net force of object ( i ) has greater force compared to object ( ii ) by
( 30 - 20 ) 10 N
Answer:
a. increasing the price of game tickets because demand is inelastic.
Explanation:
The price elasticity of demand is used in economics to show the elasticity of the quantity demand.Elasticity measure the change in the variable when another variable changes.Generally price elasticities are negative but we avoid the sign.Those good does not follows law of demand have positive sign.
So the answer of the given question is a.
a. increasing the price of game tickets because demand is inelastic.
Answer:
In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.
