The mass of the Mars exploration rover is 1063 kg . The gravity on Mars is about 0.38 that of Earth. Assuming the same slope, on which planet will the normal force exerted on the rover by the planet's surface be the greatest?a. On marsb. On Earthc. Same on both because mass is always the same

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
