m = 1400 kg, u = 10 m/s, v = 30 m/s, t = 8 s
a = (v u) / t = (30 - 10)/8 = 2.5 m/s²
F = m × a = 1400 × 2.5 = 3500 N

u = 32 m/s, v = 0, g = 9.8 m/s²
v² = u² - 2gh - 0 = 32² - 2×9.8×h
h = 1024 / 19.6 = 52.24 m

Given:
Mass m = 0.4 kg
Velocity v = 20 m/s
Kinetic Energy KE = 1/2 mv²
KE = 1/2 × 0.4 × (20)²
KE = 0.2 × 400
KE = 80 J
Final Answer: 80 J
