The net work is calculated when force is multiplied with distance. Force is calculated when mass is multiplied with the acceleration. So, the solution is as follows:
W = Fd
W = mad
W = (7.7×10³ kg)(1.4 m/s²)(31 m)
<em>W = 334,180 J</em>
Distance = speed × time
After 0.5s , horizontal distance covered is 0.5s × 18m/s = 9m
9m/ y position = cos 35° , y position = 9 ÷ cos 35° = 10.9870m (rounded up to nearest four decimal places)
After t = 1.0s:
Horizontal distance = 18m/s × 1.0s = 18m
y position = 
= 21.9740m (rounded up to nearest four decimal places)
After t = 1.5s:
Horizontal distance = 18m/s × 1.5s = 27m
y position = 
= 32.9709m (rounded up to nearest four decimal places)
After time is 2.0s:
Horizontal distance = 18m/s × 2.0s = 36m
y position = 
= 43.9479m (rounded up to nearest four decimal places)
Answer:
Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature - often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics.
Explanation:
Answer:
82.3 J
Explanation:
PE = mgh
PE = (2.80 kg) (9.8 m/s²) (3.00 m)
PE = 82.3 J
