Answer:
2.72m/s²
Explanation:
Given parameters;
Mass of box = 27.8kg
Force on box = 75.7N
Unknown:
Acceleration = ?
Solution:
Force is the product of mass and acceleration;
Force = mass x acceleration
Now insert the parameters and solve;
75.7 = 27.8 x a
a = 
= 2.72m/s²
Work is done when the ‘object moves in the same direction as the force’ an example being a man walking up a flight of stairs carrying a box of weight.
Work is not done when the direction of the applied force and the direction in which the object moves are PERPENDICULAR to each other. An example being A man carrying a load while walking, no work is done on the load in the upward direction as the load is only moving horizontally.
Thus the answer is whenever she pulls the puppy towards her

80 Meters.
Explanation:
What I did was took how many seconds the ball traveled and multiply how fast the ball was going. I actually do a lot of these questions. :))
May I please have brainlyest??
Answer:0.2167 m/s
Explanation:
Given
mass of brick M=8.5 kg
mass of toy truck m=6.5 kg
the velocity of truck u=0.5 m/s
Suppose v is the velocity after brick is landed on the truck
There is no external force acting so momentum is conserved
mu=(M+m)v
