Aweightlifter lifts a 250-kg mass 0.5 meters above his head, how much peg does the mass have? (note: g= 9.8m/s2)

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

Aforce of 8,480 n is applied to a chart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?

What are two examples of phase changes that skip a phase during transition?
