Atennis ball is hit straight upwards and undergoes a free fallmotion as it rises towards its highest point and then fall backdownward to the ground. what changes, if any, would beobserved of the velocity and the acceleration of the tennisball as it falls downward from its highest point? pick twoanswers. the acceleration the velocity

multiple

gas and liquid

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
