Answer:
The acceleration greater at the beginning of this process
Explanation:
The car when starting to move is necessary an acceleration therefore at the beginning of the movement there is an acceleration. The engine power is at a constant value so that when the car reaches the maximum speed (constant speed) at that power there will be no acceleration.
That is to say, at constant speed = zero acceleration
And of course this final null acceleration will be less than the initial acceleration so that the car starts to move
.
Answer:
This ball will attain the same range at 60°.
Explanation:
Projectile motion: when an object is thrown in such a way that it form an angle with horizon, the force act on it that is the acceleration due gravity. This type of motion is known as projectile motion.
Range: The horizontal distance is covered by an object.
Range 
u = initial velocity = 40 m/s
θ = 30°
g = gravity =9.8 m/s²
Next,
Range and u = 40 m/s
This ball will attain the same range at 60°.
Given data
mass (m) = 0.2 Kg ,
velocity (v) =300 m/s ,
calculate momentum <em>(p) = m × v </em>
<em> = 0.2 × 300</em>
<em> </em><em> P = 60 Kg. m/s</em>
<em> Momentum of the bullet is 60 Kg. m/s..</em>
