Answer:
Acceleration
Explanation:
Acceleration is the rate of change in velocity
speed is how fast an object is moving
Velocity is how fast an object is moving in the particular direction

'Doing work' is a way of transferring energy from one object to another, energy is transferred when a force moves through a distance.
If i explain with formula
Work done (J) = Energy transferred (J)
So more energy, more work done bc u transferred more energy to move the object and doing the work. and if you only use a little of energy, the work done also only a little.
Answer:
4.5m
Explanation:
Distance is the total length of path traveled or covered by a body.
So distance is a scalar quantity, it only has magnitude but no direction.
Therefore:
Total distance = 3 m + 
(3)
So;
3 + 1.5 = 4.5m
Total distance covered 4.5m by the body.
Answer:
The horizontal distance traveled by the projectile is 60 m
Explanation:
Given;
initial horizontal velocity of the projectile, Vₓ = 30 m/s
time of the motion of the projectile, t = 2 s
The horizontal distance traveled by the projectile is given by the range of the projection;
X = Vₓt
X = 30 x 2
X = 60 m
Therefore, the horizontal distance traveled by the projectile is 60 m

Force is equal to mass x acceleration. The heavyweight is packing both greater acceleration and mass than the tissue paper.
When his fist comes in contact with the paper, the tissue reacts by exerting its own opposite force, providing a tiny bit of resistance until the fist breaks it apart and passes through.
The fist, although by a a very tiny amount, is decelerated (slowed down) by the paper before it breaks through.
