A block sliding on ground where Mk = 0.243 experiences a 24.7 N
friction force. What is the
normal force acting on the block?
(Unit = N)

electromagnetic waves travel through space with vacuums. give me brainliest if right.

the area between the graph and the t axis

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
