Answer:
F = 2074.13 lb
Explanation:
Given that,
Mass of car, m = 2800 lb = 1270.059 kg
Initial speed, u = 5 mi/h = 2.2352 m/s
Final speed, v = - 1.5 mi/h = -0.67056 m/s (in opposite direction)
Time, t = 0.4 s
We need to find the magnitude of the average horizontal force (lb) exerted on the car during the impact. It can be calculated as :
or
F = -2074.13 lb
So, the required force is 2074.13 lb.
Answer:
(a) The range of the projectile is 37,336.3 m
(b) The maximum height of the projectile is 5,389.03 m
Explanation:
Given;
initial velocity of the projectile, u = 650 m/s
angle of projection, θ = 30⁰
(a) The range of the projectile is calculated as;
(b) The maximum height of the projectile is calculated as;
