120 N

Explanation: First we shoud consider the forces acted on a tree

Friction foce - acting opposite to the moving direction

Weight - Directly acting downwards

Reaction - Directly acting on upwards

For minimum required force should be equal to the friction force

F = μ R

F = 0.5×480

= 120N

Which describes the greatest amount of ice cream?
solmaris [256]

We must know that the gravity acceleration on Jupyter is g = 24.79 m/s² , on the Earth g = 9.8 m/s² and on the moon 1.62 m/s².

The weigh of an object is given by:

P = mg

Solving for m:

m = P/g

We see that for the same weight, if gravity is less, then the amount of mass is greater, because they are inversely proportional. So we conclude that the answer is:

A man starts from rest and accelerates at 4.00 m/s2. If he covers a distance of 525 m, how long does he accelerate?
rosijanka [135]

Answer:

16.2 s

Explanation:

Given:

Δx = 525 m

v₀ = 0 m/s

a = 4.00 m/s²

Find: t

Δx = v₀ t + ½ at²

525 m = (0 m/s) t + ½ (4.00 m/s²) t²

t = 16.2 s
