The speed after 10 s is 20 m/s
<h3>What is the speed after 10 s?</h3>
Given that we have the following;
force = 2800 N
Mass = 1400 kg
time = 10 s
Recall that;
F = ma
F = force
m = mass
a = acceleration
a = F/m
a = 2800 N/1400 kg
a = 2 m/s^2
Now;
v = u + at
v = ??
u = 0 m/s
a= 2 m/s^2
t = 10 s
v = at
v = 2 * 10
v = 20 m/s

Answer:
6 gallons
Explanation:
At 30 mph, the fuel mileage is 25 mpg.
After 5 hours, the distance traveled is:
30 mi/hr × 5 hr = 150 mi
The amount of gas used is:
150 mi × (1 gal / 25 mi) = 6 gal
Answer:
Explanation:
From the law of conservation of energy
Energy lost by the spring, W=Kinetic energy gained, KE+Potential energy gained, PE+Work done by friction, Fr
The required distance from A to B is
