A cart is propelled over an xy plane with acceleration components ax = 6.2 m/s2 and ay = -1.7 m/s2. Its initial velocity has com
ponents v0x = 6.8 m/s and v0y = 12.0 m/s. In unit-vector notation, what is the velocity of the cart when it reaches its greatest y coordinate?
1 answer:
Answer:
The velocity of the cart when it reaches its greatest y coordinates is 10.135m/s
Explanation:Vx=0
0=6.8m/s+(6.2m/s^2)t
t=6.8/6.2
t= 1.1secs
Vy= 12m/s +(-1.7m/s^2 )t
Vy=12 +(-1.7×1.1)
Vy=12 -1.865)
Vy=10.135m/s

Have an awesome day!
Explanation:
speed=distance/time
=50/10
=5 m/s
20 m/s is the answer this is due to displacement over change in time. Thus 200/10=20
