In a grocery store, you push a 15.5 kg shopping cart with a force of 10.5 N. If the cart starts at rest, how far does it move in 3.00 s?

The distance moved by the cart is 3.05 m

Explanation:

Given;

mass of the cart, m = 15.5 kg

applied force, f = 10.5 N

initial velocity, u = 0

time of motion, t = 3s

The final velocity of the cart is given by;

The acceleration of the cart is given by;

F = ma

a = F/m

a = 10.5 / 15.5

a = 0.677 m/s²

The horizontal distance moved by the cart is given by;

s = ut + ¹/₂at²

s = 0 + ¹/₂ (0.677)(3)²

s = 3.05 m

Therefore, the distance moved by the cart is 3.05 m

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
