Question

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 components 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?

Answer 1

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
