Answer:29.41 m/s
Explanation:
Given
Height of cliff 22.8 m
Height of river bank=2.4 m
width of river=60.0 m
Car can considered as projectile
Time travel to cover vertical distance=22.8-2.4=20.4 m



t=2.04 s
Range=60 m
Let u be the speed of car
ut=60

Net force = 50 + 50 = 100 M
Since two forces act towards the same direction , total force should be their sum amd towards the same direction as the two forces
