Answer:
13.4s
Explanation:
t = usinx/g. (X= angle , u= initial velocity)
= (147×sin63)/9.8
=13.4
Answer:
The are moving with a speed of 25 m/s after the collision.
Explanation:
assuming the mass (m) of the cars are equal, let v = 20 m/s be the velocity of the driver in the front and u = 30 m/s be the velocity of the driver behind. let V be the velocity of the cars after the collision.
then, by conservation of linear momentum:
m×(v + u) = V×2×m
(v + u) = V×2
V = (v + u)/2
= (20 + 30)/2
= 25 m/s
Therefore, the are moving with a speed of 25 m/s after the collision.
