Answer:
The rolling basketball has greater momentum.
Explanation:
The momentum of an object is defined as the product of mass and velocity.
Given that the bowling mass has a greater mass than the basketball,
The bowling ball is at rest, so the velocity if the ball is zero.
The basketball is rolling, it has some velocity associated with it.
Therefore, the momentum of the bowling ball is zero.
The basketball has some momentum associated with it.
Hence, the rolling basketball has greater momentum.
C. endothermic
An endothermic process takes heat from the surroundings while an exothermic process gives out heat to the surroundings.
The maximum speed of the donkey is 10.72m/s
The question is based on the principle of motion in one dimension and hence formulas of motion in one dimension can be applied.
It is given that donkey attains an acceleration of 1.6 m/s^2
The time taken to accelerate to given speed is 6.7 seconds
We use the formula v=u + at to find the fastest speed
v is the final or maximum speed
u is the initial speed which in this case is 0 as the donkey is at rest
a is the acceleration of the donkey
t is the time taken in seconds
v = u + at
v= 0 + 1.6 x 6.7
= 10.72 m/s
Hence the donkey obtains the speed of 10.72 m/s
